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 use of thermoluminescent dosimeters (TLDs) to determine gamma-ray heating in a zero-power fast-reactor environment is considered. Generalized cavity-ionization theory is used to determine the relationship between the gamma-ray heating in the medium and the energy deposited in a TLD placed within the medium. The relationship is a function of the composition of the TLD and the surrounding medium, the size of the TLD, and the gamma-ray spectrum in the medium. Calculations are presented for several combinations of these variables. Data on the response of TLD materials to fast neutrons are reviewed. The fast-neutron-induced contribution to the thermoluminescent output relative to the gamma-ray-induced contribution is investigated. The relationship between the thermoluminescent response and the energy deposited in the dosimeter is also discussed.
