Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

A system has been developed for the production of 99mTc based on distributed electron accelerators and thermal separation. The radioactive decay parent of 99mTc, 99Mo, is produced from 100Mo by a photoneutron reaction. Two alternative thermal separation processes have been developed to extract 99mTc. Experiments have been performed to verify the technical feasibility of the production and assess the efficiency of the extraction processes. A system based on this technology enables the economical supply of 99mTc for a large nuclear pharmacy. Twenty such production centers distributed near major metropolitan areas could produce the entire U.S. supply of 99mTc at a cost less than the current subsidized price.
