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.

An array of micrometric diodes coupled to a residual energy measurement stage was proposed for solid-state microdosimetry. Each diode has a sensitive volume of a cylindrical shape (9 m in nominal diameter) in order to reproduce that simulated by a cylindrical tissue-equivalent proportional counter (TEPC). The silicon microdosimeter was irradiated coupled to a polyethylene converter with monoenergetic neutrons of several energies. The spectra of the energy imparted to the segmented telescope were corrected for tissue equivalence through an optimized procedure that exploits the information from the residual energy stage. A geometrical correction was also applied. The dose-mean lineal energy values were qualitatively compared with literature data. The silicon microdosimeter was also covered with a tissue-equivalent plastic (A150) and with a nylon converter. The results showed a contribution of heavy recoils (mainly carbon and nitrogen nuclei) generated in the tissue-equivalent plastic lower than that measured by the TEPC, owing to their stopping in the titanium-based dead layer of the silicon device.
