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.

Total gamma-ray attenuation coefficients for five different elements were measured for energies 6.02-, 7.28-, 7.72-, 8.49-, 9.3-, and 9.88-MeV gamma rays. The nuclear resonance scattering method was used in the attenuation of photons for the two energies, 7.28 and 8.49 MeV. For the other energies the direct narrow beam method was used. The total attenuation coefficients were measured with an average uncertainty of 0.6% and appeared to be in better agreement with the tabulated values of Hubbel and Berger than those of Storm and Israel.
