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 general calculational model describing the effects of neutrons and gamma rays on self-powered prompt-responding coaxial in-core radiation detectors is presented. The model accounts for external gamma-ray interactions within a detector and the subsequent emissions of Compton electrons and photoelectrons. The model also includes neutron-capture gamma-ray and internal-conversion electron emissions. The effect on a detector’s sensitivity of space charge within its insulator is considered. A pseudopotential on the central electrode is introduced to account for Z-dependent variations in the space-charge distribution. Calculated neutron and gamma sensitivities of several in-core detectors are compared with experimental sensitivities. The comparisons are sufficiently satisfactory to label the model as successful in its predictions.
