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.

Several filtered-beam facilities exist that provide monoenergetic neutrons at 186 eV; 2, 25, 55, and 144 keV; and at 2.2 MeV. This range of energies can be extended by using natural uranium as a filter in conjunction with suitable secondary filters and scattering foils. The range of energies obtainable with uranium lies between 100 eV and 2.5 keV. Neutron fluence rate and beam purity estimates are provided at the most useful energies obtainable with uranium. Dose equivalent rates and kerma rates are also evaluated, and it is concluded that such a range of filtered beams would have many useful applications in radiation protection.
