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.

The gamma-ray scattering technique has shown promise for the continuous measurement of atmospheric density from space vehicles. To understand and optimize the parameters of this technique, mathematical models have been derived and used to study design parameters such as gamma-ray source energy, source-to-detector separation, detector discriminator settings, and shield effectiveness. The predicted effects agree generally with the experimental results obtained in feasibility studies, and mathematical modeling promises to be an effective means for optimizing the design of the gamma-ray scattering technique for measuring atmospheric density.
