ITEM 1. BUSINESS

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This periodic report contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, business strategies, operating efficiencies or synergies, competitive positions, growth opportunities for existing products, plans and objectives of management. Statements in this periodic report that are not historical facts are hereby identified as forward-looking statements.

Overview

Princeton was founded in February 2005 to acquire the detector and microanalysis business of Outokumpu Oyj. In February 2005, Princeton completed the acquisition of the detector and microanalysis business from a subsidiary of Outokumpu Oyj. As part of the acquisition of the business, Princeton retained the management and scientific staff of the subsidiary's detector business unit to continue to operate the detection and microanalysis business. Additionally, Princeton assumed the lease on the premises occupied by Outokumpu Oyj. The facilities were located in Rocky Hill, New Jersey and served as the company's offices, manufacturing and research facilities. In March 2006, Princeton moved its offices to 303C College Road East, Princeton, New Jersey where its management, manufacturing and research and development are currently located.

As part of the goal in acquiring the detector business, following the acquisition, Princeton divested the Microanalysis business to a subsidiary of Bruker Biosciences Corp. so that management could focus on, what it believed to be, the more profitable detector business within the Homeland Security industry.

In September 2006, Princeton restructured its corporate status by creating a Nevada corporation called Princeton Security Technologies, Inc. to be the holding company of Princeton Gamma Tech Instruments, Inc. Management reincorporated in Nevada and completed a stock exchange making Princeton Gamma Tech Instruments the wholly owned subsidiary of the Nevada corporation. Princeton's primary focus is on the X-ray and Gamma-ray Detectors and Spectroscopy systems, Radioactive Isotope Identifier products. Our products detect radioactive and other nuclear materials in various security and environmental settings.

Products

Through the purchase of the detector business, Princeton acquired X-ray and Gamma-ray Detectors and Spectroscopy systems, and Radioisotope Identifier products. More importantly, we also acquired the management and scientific teams responsible for the development of this technology. Currently we produce both individual detection units as well as component parts for larger units manufactured and sold by other companies.

The uses for our products encompass a variety of industrial, commercial and security concerns ranging from the homeland security need to detect concealed radioactive material, to silicon wafer fabrication companies that use our products and components to analyze silicon wafers for defects.

The nature of our technology allows our products to encompass a variety of uses. Our products typically have three basic technologies that can be combined to create a detection unit or system. Each of our products contains a sensor or a detector, electronic circuitry to process the signal from the sensor and firmware or software to analyze and interpret the processed signal. Princeton has design, development and manufacturing capability in all three technology areas. By focusing on these three core competencies used in detectors and components, we are able to design products for multiple industries and users.

As part of our core technology, we have developed the internal capability to produce a high purity germanium radiation detector, Sodium Iodide and Lanthanum Bromide scintillators, which are the key component in Gamma-ray detection systems. We also have an internal capability to process x-ray detectors, as well. These capabilities allow us to compete with the limited number of companies who have the ability to work with these types of sensors. These sensors are most frequently used to detect radioactive isotopes.

Currently, our product line includes the following component and detectors:


-	Category 1: Radioactive Isotope Identifier Products.
	The current product is termed the SAM Radioactive Isotope Identifiers (RIID). This hand-held instrument is a self-contained radiation detector, low-noise signal processor, and user interface. Our proprietary analysis software provides an intuitive color display suitable for both First Responders as well as more technically trained Health Physicists. This product and product versions are mainly used for large homeland security market applications, as well as for environmental, industrial and medical purposes. Last year a common application was to detect radioactive isotope leaks coming from Nuclear Power plants as a result of Fukushima nuclear power plant disaster in Japan. The Company has customized its RIID to detect such isotopes according to the required specifications from the local Health authorities. This product detects neutron and gamma radiation from over 100 isotopes. The SAM was designed to meet the latest American National Standards Institute "ANSI" and other government standards for portable radiation detection equipment.

	We previously introduced a Fixed Installation unit, called Area Monitor, to our product offering. That product is being offered and used in e.g. building security applications, hospitals, industrial applications and generally in security applications where an identified area or facility needs to be secured. A new application is a vehicle and cargo Portal monitoring for security purposes. Area Monitors can also be used to detect the Radioactive Isotopes coming from Nuclear Power plants as well as measuring the Radiation level in the food items e.g. water, milk, vegetables, fish, beef etc.

-	Category 2: Nuclear/ Gamma-ray detectors and spectrometers:
	Princeton is one of the handful of companies worldwide that manufactures High Purity Germanium Detectors and associated electronics and software for the most sensitive and accurate detection and analysis of radioactive samples in a laboratory environment. A typical application is the measurement of very low-levels of radioisotopes in soil, water or geological samples to determine the efficacy of radioactive waste cleanup or to conduct geophysics research. This type of lab-based instrumentation is also used by the nuclear power industry for on-line monitoring. Customers include Federal and State governmental authorities, research laboratories and large corporations.

	We introduced last year a new version of High Purity Germanium detector system with a Sterling cooler. This system is more customer friendly and eliminates the usage of Liquid Nitrogen in the detector cooling procedure.

-	Category 3: X-ray detectors and spectrometers.
	These products address the research and industrial analysis need in the Microanalysis or XRF market. The Microanalysis Market is the branch of industry and scientific research that requires the non-destructive analysis of materials on a sub-millimeter dimensional scale.

	The non-destructive testing of materials by X-ray analysis utilizes a range of detector products from small hand-held units to large systems installed on a Synchrotron and used for the fundamental research of materials. Princeton supplies both detector components as an OEM supplier and also complete X-ray spectrometer systems. Applications include quality control (e.g., for Silicon wafer fabrication), fundamental material research (e.g., on a synchrotron), and industrial control and monitoring, (e.g., engine wear analysis). A typical application is analyzing various metals for quality or research purposes. Company's core competence is high end Silicon Drift Detectors and other custom design x-ray detectors.

Markets

The market for our products is broad and encompasses both industrial, commercial and security concerns. Although our products are sold world-wide, current emphasis by the United States government on homeland security measures leads us to believe the US market will be strong for many of our detectors.

Our hand held and fixed installation detectors have the ability to check for various radiation in packages, containers or environmental areas. This will allow them to be used for multiple purposes including use by homeland security companies in checking for items such as dirty bombs.

Homeland Security market generally includes: law enforcement authorities, first responders, HAZMAT teams, governmental agencies and companies that work with such agencies. This is a growing marketplace particularly in the realm of radiation and special nuclear material detection. SAM Isotope Identifier, Area Monitors and as well as some High Purity Germanium detectors are targeting this segment, which is sizeable enough to support several players.

Additionally, we produce components that are used by other companies in larger detection units in multiple discipline areas. Both Gamma-ray and X-ray detectors and systems are considered to be a part of analytical instruments market segments. Our products and systems address needs for a smaller market segment within the analytical instruments marketplace aimed at industrial and research usage.

The recent Nuclear Power plant crisis in Japan has resulted in an increased level of interest in radiation detection related to the Nuclear Power plants. This market is currently very significant. Due to the leaked isotopes, which are extremely dangerous for people living close to those areas, coming from Nuclear Power plants we see that our products have a huge potential to detect such isotopes; whether RIIDs, Fixed Area Monitors or High Purity Germanium based systems are being deployed in such circumstances. This market has been there for decades but not until recently it has become more critical due to serious recent Nuclear Power plant problems in Japan.

Competition

The environment for our products and services is intensely competitive. Although the complexity of the products we produce limits the number of companies we compete with, the companies with competing technology are generally larger and often subsidiaries or divisions of very large multinational companies. Our competitors' size and association with large multinational companies creates advantages over us in the ability to access potential customers. Many potential customers already purchase products either directly from our competitors or from another subsidiary of these large multinational companies creating natural inroads to sales that we do not possess.

Given our relative size versus our competitors, we often have to seek niche markets for our products or focus on selling components to be used in our competitors' larger detection units. We believe, however, that our technology and experience in the detection industry allows us to be competitive in our markets. However, until we have more funding, we will be limited in our ability to expand our market penetration and to be able to introduce new products.

We believe our main competitors are ICX Technologies , recently acquired by a publicly held US company Flir Systems Inc., with a large selection of radiation detection products and technology; Canberra Industries, Inc., a subsidiary of French Areva group, specializing in larger nuclear projects and Radiation Identifying detector technology to the Homeland Security market; Ortec, a division of Ametek (Advanced Measurement Technology, Inc.), offering nuclear detection products to the Homeland Security market and Thermo Fisher Scientific, a large US based publicly held company, which sells radiation detection as well as other Homeland Security technology products.

In addition to the above competitors, there are several other companies that offer competing products in each of our market segments. Given the complexity of our products, we do not foresee substantial new competitors entering the broad market but instead see the current competitors becoming more aggressive as the markets continue to expand.

Future Growth Plans and Markets

By purchasing complex technology developed over the last thirty years, we believe we have the capability to enter into a growing marketplace in the Homeland Security as well as overall detector field. We are hopeful we can provide improved focus to products and related technology that was not receiving the attention or funding it required while operating as a subsidiary of a large multinational company whose primary focus was moving in another direction. We have spent the last four years improving upon the technology acquired; further developing new innovative products and refocusing our strategy on the growing need for sophisticated and dedicated detection units and components. We are hopeful this focus will allow us to be at the forefront of increased spending on detection devices for the commercial and homeland security markets. Three markets we see as new uses for our products are in the homeland security marketplace where there is a continuous need for dangerous radioactive and nuclear material to be identified by several authorities; Nuclear power plant market and in the "quality control" area where testing equipment has become a crucial part of the manufacturing process.

Although security issues have been around before, there is a new and on-going need to be able to detect various radioactive isotopes in different security and environmental settings. This marketplace is expanding throughout the world. This need is being created not only from the fear of terrorism but also from the expansion of the use of various chemicals and radiation in the manufacturing environments and the need to assure radiation is not being released inadvertently into the environment. We have created several detectors and related components aimed directly at this need and will continue to work on the development of even more sophisticated devices for this expanding market.

The past Nuclear Power plant crisis in Japan has resulted in an increased level of interest in radiation detection related to the Nuclear Power plants. Due to the leaked isotopes, which are extremely dangerous for people living close to those areas, coming from Nuclear Power plants we see that our products have a potential to detect such isotopes; whether RIIDs , Fixed Area Monitors or High Purity Germanium based systems are being deployed in such circumstances. This market has been there for decades but not until last year has it become more critical due to serious recent Nuclear Power plant problems in Japan. Therefore we believe that this market will provide company real growth opportunities.

As manufacturers continue to create more complex products relying heavily on automation, we believe that they will continue to require products such as detectors and testing equipment capable of evaluating the quality of the products produced. We have seen this in the silicon wafer fabrication process where we currently provide component parts to help detect any defects in the chips. Another new application for us is the detection of radioactive raw material in a manufacturing process within a marble industry or steel industry. We believe these "quality control" products will continue to see increasing demand and the use of our products will expand.

Princeton's plan of operation going forward consists of a two tier approach including a marketing strategy and a sales strategy.

Our marketing strategy includes a number of defined processes, and will leverage existing marketing plans from Princeton and affiliate companies. Campaigns run on a regular basis will include a tradeshow schedule, direct mail, email, telemarketing and direct sales calls, user groups and radiation detection workshops. Furthermore, our marketing efforts will also introduce a one-to-one customer driven outline to address the network and support needs of each customer.

We intend to prioritize customer service and make it a key component of our marketing programs. We believe that providing our customers with what they want, when and how they want it, has been fundamental in the development of our reputations in the industry.

Because we want to develop close working relationships with our customers, we want to establish accounts in as personable a way as possible. It is for this reason that we will overwhelmingly emphasize in-person sales visits.

We will closely integrate all of our marketing and sales efforts to project a consistent image of our company and a consistent positioning of our products and services. Furthermore, to support our marketing initiatives and effect legislative actions, we plan to participate in several Washington, D.C. based DHS (Department of Homeland Security) events directly or indirectly via our partners and consultants, and utilize a lobbyist in Washington, D.C. with contacts in the security business.

Our sales strategy includes focusing initial efforts on the top level decision maker or influencer at each targeted government agency. Princeton will also work with DHS to determine which government agencies are appropriate for immediate deployment of advanced technology.

We plan to use the following business development strategies:


1)	Use internal contacts or existing customer base within government agencies to identify new opportunities. Once a new opportunity or person is being identified we can determine if the potential new sales opportunity will be handled directly or by our OEM partners or representatives.

2)	Once the proper Points of Contact have been qualified, an account executive or our partners will present the technology and overcome sales objections. During this time the sales person will confirm the details of the opportunity, if any. Onsite demonstrations will be critical in customer acceptance.

3)	Onsite demonstrations will include an account executive and possibly a sales engineer. We currently sell to several state and federal agencies including the Environmental Protection Agency, Department of Energy, NASA, National Institute of Standards and Technology , Pacific Northwest National Laboratory, Los Alamos National Laboratory, Princeton Plasma Physics Lab, Idaho National Lab, US Geological Survey and The Savannah River Company.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Plan of Operation.

General.

Certain statements in this Report constitute "forward-looking statements." Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Factors that might cause such a difference include, among others, uncertainties relating to general economic and business conditions; industry trends; changes in demand for our products and services; uncertainties relating to customer plans and commitments and the timing of orders received from customers; announcements or changes in our pricing policies or that of our competitors; unanticipated delays in the development, market acceptance or installation of our products and services; changes in government regulations; availability of management and other key personnel; availability, terms and deployment of capital; relationships with third-party equipment suppliers; and worldwide political stability and economic growth. The words "believe", "expect", "anticipate", "intend" and "plan" and similar expressions identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates under different assumptions or conditions. The Company believes there have been no significant changes during the year ended December 31, 2011.

The Company's accounting policies are more fully described in Note 1 of the consolidated financial statements. As discussed in Note 1, the preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions about the future events that affect the amounts reported in the consolidated financial statements and the accompanying notes. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual differences could differ from these estimates under different assumptions or conditions. The Company believes that the following addresses the Company's most critical accounting policies.

We recognize revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, "Revenue Recognition" ("SAB 104"). Under SAB 104, revenue is recognized at the point of passage to the customer of title and risk of loss, when there is persuasive evidence of an arrangement, the sales price is determinable, and collection of the resulting receivable is reasonably assured. We recognize revenue as services are provided with specific long lead time orders.

Our allowance for doubtful accounts is maintained to provide for losses arising from customers' inability to make required payments. If there is deterioration of our customers' credit worthiness and/or there is an increase in the length of time that the receivables are past due greater than the historical assumptions used, additional allowances may be required. For example, at December 31, 2011, every additional one percent of our accounts receivable that becomes uncollectible would reduce our operating income by approximately $2,034

We account for income taxes in accordance with FASB ASC Topic 740, "Accounting for Income Taxes" (ASC Topic 740). Under ASC Topic 740, deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets will be reflected on the balance sheet when it is determined that it is more likely than not that the asset will be realized. A valuation allowance has currently been recorded to reduce our deferred tax asset to $0.

Our Business Growth

For the 12 month period ending December 31, 2011 our sales increased to $4,157,675 from $2,565,512. With the increased sales, our Net Profit was $495,599 compared to a Net Profit of $44,700 for the same 12 month period in 2010. Our Radioactive Isotope Identifiers had the biggest sales volume of all product categories with the sales of $3,078,159, and the second biggest category is the Nuclear products with the sale of $622,424 for the 12 month period. The third largest sales category is X-ray Detectors. The largest growth for the 12 month period was in Radioactive Isotope Identifiers, where the sales grew to $3,078,159 from $1,294,504 which represents 138% growth. This was due to enhanced sales distribution as well as introducing the new and more competitive products and applications to the market, as well as expanding more aggressively into the new geographical markets such as China.

The Company expects the growth to continue in the year 2012. Most of the growth will come from Radioactive Isotope Identifier products. We also expect X-Ray Detectors to generate a reasonable amount of growth in Sales. We expect the Nuclear Products to generate a moderate growth or remain at the same level as year 2011.

Results of Operations

Total sales increased $1,592,161 for the comparable 12 month period in 2011 from 2010. Our Operating expenses increased by 24% for the year ended December 31, 2011, to $1,490,014 from $1,203,034 for the 2010 year end. We had a net profit of $495,599 for the calendar year 2011 compared to $44,700 for the same period in 2010.

The profit was a reflection of the efforts to control our operating expenses, as well as move more profitable products from the research and development stage and early stage commercialization into market. We still will need increased sales to reach profitability and cover all of our operating cost.

General and administrative expenses increased 20% from $629,885 for calendar year 2010 to $758,120 for the calendar year 2011. Marketing expenses increased 41% from $246,109 to $347,002 in the year 2011 and our Research and Development expenses increased 24% from $304,262 to $376,727 in the year 2011. We expect our expenses to increase in the future as we expand our sales revenues and our operations.

Since we are in the initial phases of product sales for some new products, we are hopeful sales will increase and be able to cover somewhat increased operating cost.

Off Balance Sheet Arrangements.

We had no off balance sheet arrangements during the year ended December 31, 2011.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, which consists of our President /CEO and Principal Financial Officer evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our President and Principal Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective such that the information required to be disclosed by us in reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to our management, including our CEO and Principal Financial Officer, as appropriate to allow timely decisions regarding disclosure. A controls system cannot provide absolute assurance, however, that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected; however, our CEO and Principal Financial Officer believes our controls and procedures provide reasonable assurance as set forth above..

Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

Our management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2011. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control - Integrated Framework. Based on this evaluation, our management concluded that, as of December 31, 2011, our internal control over financial reporting was effective.

This annual report does not include an attestation report of the Company's registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by the Company's registered public accounting firm pursuant to temporary rules of the Security and Exchange Commission that permit the Company to provide only management's report in this annual report.

Changes in internal control over financial reporting

There have been no changes in internal control over financial reporting that occurred during the last fourth fiscal quarter that has materially affected, or is reasonably likely to materially affect, the internal control over financial reporting.

PART III

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS AND COPRORATE GOVERNANCE

The following table sets forth the name, age, and position of each executive officer and director and the term of office of each director of Princeton:


Name	Age	Position	Director Since
Juhani Taskinen	55	CEO, Director	2005
David Brown	40	Director	2005
Trupti Mehta	53	Principal Financial Officer	2007

The term for each officer is for one year and until a successor is elected at the annual meeting of the board of directors and is qualified, subject to removal by the board of directors.

Princeton does not have a standing audit, nominating or compensation committee. The size of Princeton's board has not permitted the board of directors to divide up some of the corporate governance provisions. It is anticipated as our business expands, that board of director committees will be formed. At this time, however, the exact timing and the nature of such committees is unknown. We will form an audit and compensation committee. We currently have one independent director and will seek additional directors with financial and accounting knowledge to serve on these committees. At this time we do not know of any persons who will be nominated.

Biographical information

Set forth below is certain biographical information with respect to Princeton's existing officer and directors.

Juhani Taskinen -- Mr. Taskinen is the founder of Princeton Gamma-Tech Instruments, Inc., and is our Chief Executive Officer and Chairman of the Board of Princeton Security Technologies, Inc. Mr. Taskinen has been the President of Finn-Partners, Inc. since 1993. Finn-Partners, Inc. is a management consulting and investment firm that specializes in management and financial consulting in the merger and acquisition field. Mr. Taskinen was also a Senior Advisor for Lehman Brothers in Scandinavia during 2003-2004, and also held executive positions within Nokia Corporation prior to founding Finn-Partners, Inc. Mr. Taskinen holds a BSc (economics) as well as an MBA from Pepperdine University.

David Brown -- Mr. Brown joined us in March 2005 as an investor and in April 2005 became a member of our board of directors. Mr. Brown has been the President of Berkeley Nucleonics Corporation since 1993. Berkeley Nucleonics specializes in nuclear detection products and instruments for Federal agencies, such as the US Secret Service, FBI, and Department of Defense as well as to the Homeland Security market. Berkeley Nucleonics has grown steadily during Mr. Brown's presidency and has also expanded to the international market. Mr. Brown holds a BA in Entrepreneurial Management from San Francisco State University.

Trupti Mehta - Ms. Mehta joined the company in September 2007 and is our Principal Financial Officer. Prior to joining the Company she was the Finance Manager with Innovative Folding Cartons Co. Inc. Ms. Mehta holds a Bachelors Degree in Accounting from the University of Bombay, India.

There are no family relationships among our officers and directors.

Our current directors are Messrs. Taskinen and Brown. Under our bylaws, directors are elected annually at the annual meeting of shareholders to hold office for one year or until their successors are duly elected and qualified. Board vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by a majority vote of the directors then in office, even if less than a quorum, or by a sole remaining director. The executive officers are appointed by the Board and serve at their discretion.

Term of Office.

The terms of office of the current directors shall continue until the annual meeting of stockholders, which has been scheduled by the Board of Directors to be held in June of each year. The annual meeting of the Board of Directors immediately follows the annual meeting of stockholders, at which executive officers for the coming year are elected. We believe our directors' business experience, particularly, the time spent in our industry qualifies them as directors of the Company.

Significant Employees.

There are no significant employees.

Family Relationships.

There are no family relationships between any of our directors or executive officers.

Involvement in Certain Legal Proceedings.

During the past five years, none of our present or former directors, executive officers or persons nominated to become directors or executive officers:

(1) Filed a petition under the federal bankruptcy laws or any state insolvency law, nor had a receiver, fiscal agent or similar officer appointed by a court for the business or property of such person, or any partnership in which he was a general partner at or within two years before the time of such filing, or any corporation or business association of which he was an executive officer at or within two years before the time of such filing;

(2) Was convicted in a criminal proceeding or named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses);

(3) Was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated, of any court of competent jurisdiction, permanently or temporarily enjoining him or her from or otherwise limiting his involvement in any type of business, securities or banking activities;

(4) Was found by a court of competent jurisdiction in a civil action, by the Securities and Exchange Commission or the Commodity Futures Trading Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Securities and Exchange Commission has not been subsequently reversed, suspended, or vacated.

Compliance with Section 16(a) of the Exchange Act.

To our knowledge, during our past fiscal year and since then, all filings required to be made by members of management or others pursuant to Section 16(a) of the Exchange Act, have been duly filed.

Code of Ethics.

We are in the process of establishing a code of ethics and should have it in place during the third quarter of 2012.

Nominating Committee.

We have not established a Nominating Committee because we believe that our two Board of Directors members are able to effectively manage the issues normally considered by a Nominating Committee.

If we do establish a Nominating Committee, we will disclose this change to our procedures by which shareholders may recommend nominees to our board of directors.

Audit Committee.

We do not have an Audit Committee separate from our Board of Directors because of our present limited operations.

The carrying amount of the Company's cash and cash equivalents, accounts receivable, prepaid expenses and other current expenses, and the current portions of notes payable approximate their estimated fair values due to their short-term maturities.

Concentrations of Risk

At December 31, 2011 approximately 67% of the Accounts Receivable was from foreign customers. Amongst the domestic customers, the Company had one customer that accounted for 14% and another customer that accounted for 11% of the accounts receivable. The Company performs ongoing credit evaluations of its customers' financial condition and generally requires advance payments from its customers.

NOTES TO CONSOLIDATED FIANCIAL STATEMENTS (Continued)
December 31, 2011 and 2010

The Company considers all highly liquid debt instruments with an original maturity of three months or less to be cash equivalents. The Company maintains cash and cash equivalents at various financial institutions in New Jersey. Accounts at each institution are insured by the Federal Deposit Corporation up to $250,000. At December 31, 2011 the Company's uninsured cash balance was $78,894. The Company has not experienced any significant losses on cash and cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts

Most of our Customers have agreements of Payment of a portion of the total Sale on acknowledgement of the Order. Our normal allowance for doubtful debts would be 1% of total receivables.

Inventory

The Company maintains an inventory comprised of raw materials used to make detectors and spectroscopy systems, radioisotope identifiers and chemical analyzers, work in process and finished goods, as well as service parts. Inventory is recorded at lower of cost or market and is reconciled annually at the close of each fiscal year. The Company periodically analyzes its inventory for potential impairment, assessing the appropriateness of turnover rates and recoverability of costs based on sales cycles and standard holding time for each item. Obsolete and slow moving inventory was written off during the year.

Property, Plant and Equipment

The Company capitalizes property, plant and equipment and depreciates the cost of these items over their useful lives. The useful lives run from 3 to 7 years. The cost is expensed equally over the useful life of each item.

Revenue Recognition

The Company recognizes revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, "Revenue Recognition" ("SAB 104"). Under SAB 104, revenue is recognized at the point of passage to the customer of title and risk of loss, when there is persuasive evidence of an arrangement, the sales price is determinable, and collection of the resulting receivable is reasonably assured. We recognize revenue as services are provided. Revenues are reflected net of coupon discounts.

Revenues received as advances on acknowledged sales orders are termed as Deferred Revenue.

Income taxes

The Company is subject to United States income taxes.

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance for any tax benefits for which future realization is uncertain.

Note 3 Recently Issued Accounting Pronouncements

The Company has reviewed the Accounting Standards Updates through 2011-2012 and have evaluated their effect on the Company's financial statements. Currently, no accounting standards updates materially affect the Company's financial reporting.

December 31, 2011 and 2010

In 2010, the Company issued 340,000 shares of common stock out of which 60,000 were in payment of a debt and 280,000 were issued to its employees in accordance with an agreement between such employee and the Company.

In 2011, the Company issued 440,000 shares of common stock out of which 50,000 were in payment of a service and 390,000 were issued to employees.

The Company issued a dividend of $.01 per share in December 2011.

Earnings Per Share

The Company accounts for earnings per share under the provisions of ASC Topic 260, "Earnings Per Share", which requires a dual presentation of basic and diluted earnings per share. Basic earnings per share excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed assuming the conversion of convertible preferred stock and the exercise or conversion of common stock equivalent shares, if dilutive, consisting of unissued shares under options and warrants. Basic and diluted losses are the same as the inclusion of unissued warrants and options in the denominator would be anti-dilutive.

Note 9 Provision for Income Taxes

ASC 740 requires the reduction of deferred tax assets by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. In the Company's opinion, it is uncertain whether they will generate sufficient taxable income in the future to fully utilize the net deferred tax asset. Accordingly, a valuation allowance equal to the deferred tax asset has been recorded. The total deferred tax asset is calculated by multiplying a 44% combined marginal tax rate by the cumulative NOL of $1,235,280. The total valuation allowance is equal to the total deferred tax asset which includes various temporary differences.

The tax effects of significant items comprising the Company's net deferred taxes as of December 31, 2011 and 2010 were as follows:
