ATLANTA, GA–(March 27, 2014) – Perma-Fix Medical Corporation, a wholly owned subsidiary of Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) today announced successful validation of its process to produce Technetium-99m (Tc-99m) from Molybdenum-99 (Mo-99) using standard reactors at two of the premier research institutions in Poland and the United States. The first set of tests were conducted at POLATOM in Warsaw, Poland and reaffirmed previous testing that the Company’s proprietary resins could withstand high levels of radiation, while meeting regulatory standards for the production of Tc-99m. The second set of tests, conducted at the Missouri University Research Reactor (MURR) in Columbia, Missouri, reinforced the POLATOM results and demonstrated higher elution efficiencies. We have filed patent applications in connection with our new process to produce Tc-99m from Mo-99.

Dr. Louis F. Centofanti, CEO of Perma-Fix Medical and Perma-Fix Environmental Services, commented, “These results further validate the strength of our technology, which we believe has the potential to reshape the global supply chain of Tc-99m in the United States and around the world. We believe the new process is a less expensive process and does not require the use of government-subsidized, weapons-grade materials. We believe our process also addresses important issues associated with current production methods. Our process can be performed in most standard research reactors, which should help solve concerns regarding supply shortages of Tc-99m around the world. Second, our process does not utilize Highly Enriched Uranium (HEU) or Low Enriched Uranium (LEU) targets, which are frequently cited as proliferation risks. Lastly, we believe our process eliminates many environmental concerns associated with the current Mo-99 production methodology, including issues around reprocessing of target materials and production of high level waste requiring permanent disposal not currently provided for.”

By way of background, Tc-99m is the most widely used medical isotope in the world. It allows medical practitioners to image internal body organs and is used in 80-85% of the 25 million diagnostic nuclear medical procedures each year in the U.S. alone. Common procedures include: cardiac imaging; cancer detection bone scans; gastrointestinal issues; and imaging of the brain, kidney, spleen and infections. The radioisotope market in Europe alone is expected to reach $1.6 billion in 2017, up from $1.1 billion in 2012.

Nearly all of the world’s supply of Tc-99m comes from the thermal fission of highly enriched uranium (HEU) targets in a small number of highly specialized reactors. The current process is costly and has proven an unreliable source of radioactive material leading to severe worldwide shortages. The scheduled closure of the NRU reactor in 2016 and the OSIRIS reactor in France in 2018 are expected to have a further impact on the manufacturing and supply of these isotopes. The current process also raises serious proliferation concerns related to the threat associated with international production, transportation and/or use of HEU in the production of medical isotopes.

We believe that Perma-Fix’s technology overcomes these issues by using neutron capture to activate natural Molybdenum, a common metal, to produce Mo-99, which decays into Tc-99m. Unlike conventional processes, the Perma-Fix Medical process can be produced locally using standard research and commercial reactors, thereby eliminating the need for special purpose reactors. The new process encompasses the full production cycle, from reactor to final medical supply, and should be easily deployable around the world.

To overcome past issues with neutron activation of Molybdenum, Perma-Fix has developed a specialized resin that is radiation resistant and holds large quantities of Molybdenum, but at the same time releases almost 90% of the Tc-99m as it forms from the decay of Mo-99. The resin, loaded with the activated Mo-99, is placed in a Technetium generator and slowly washed with a saline based solution. The eluent solution containing Tc-99m has been shown to meet targeted USP and EUP standards for Pertechnetate.

About Perma-Fix Medical
Perma-Fix Medical with headquarters in Atlanta, Georgia (USA), is a subsidiary of Perma-Fix Environmental Services, a NASDAQ listed company. It was formed to develop, obtain FDA and other regulatory approval and commercialize a new process to produce Technetium-99 (Tc-99m), the most widely used medical isotope in the world. The new process is expected to solve worldwide shortages of Tc-99m as it is less expensive, does not require the use of government-subsidized, weapons-grade materials and can be easily deployed around the world using standard research and commercial reactors, thereby eliminating the need for special purpose reactors.
