Positron Corporation : POSITRON/MANHATTAN ISOTOPE TECHNOLOGY RECEIVES LICENSE AMENDMENT APPROVAL FOR STRONTIUM-82

MIT Initiates 2012 Sr-82 Validation Project

FISHERS, INDIANA-January 27, 2012 (BUSINESS WIRE)-Positron Corporation (OTCBB:POSC), a leading molecular imaging healthcare company, specializing in the field of nuclear cardiology, is pleased to announce that on January 23, 2012, its wholly owned subsidiary, Manhattan Isotope Technology (MIT), received approval of its radioactive materials license amendment. The Texas Department of State Health Services- Radiation Control Program granted the amendment approval.

This specific amendment will now permit for the receipt and processing of solutions, which contain Sr-82 and multiple other radioisotopes. Over the next six months MIT will obtain Sr-82 target solutions, from foreign irradiators, for final purification into Active Pharmaceutical Ingredient (API) grade Sr-82 at the MIT facility in Lubbock, TX.

During proton irradiation to produce Sr-82, many other radioisotopes are co-produced. These additional isotopes are removed from Sr-82 during radiochemical processing. The previous MIT radioactive materials license was limited to two radioisotopes: Sr-82 and Sr-85. The new amended license broadens the scope of isotopes permitted on site and allows MIT greater flexibility in this validation phase.

Commenting on the significance of the license approval, MIT President and Positron Pharmaceutical, Chief Technical Officer, Jason Kitten stated, "Positron and MIT are rapidly implementing a new foundation for cardiac PET by increasing the supply and reliability of Sr-82. Positron has designed a superior integrated business model for the reliability and expansion of cardiac PET in the US. With this latest license approval, MIT has significantly accelerated Positron's Sr-82 mission and will begin supporting Sr-82 supply in 2012, further strengthening Positrons goal of solidifying cardiac PET's progression in the US."
