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.

Buildup factors for energy deposition in water and aluminum and for exposure in concrete are presented for monoenergetic, point isotropic gamma-ray sources. The buildup fac. tors were evaluated using the method of moments and are tabulated for energies from 0.03 to 10 MeV and distances out to 50 mean -free-paths from the source. Empirical representations of these buildup factors are developed using Berger’s formula. Fitting parameters are tabulated for each material as a function of source energy.
