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.

Rapid nondestructive mineral analysis can be performed with use of a 252Cf neutron source and a lithium-drifted germanium [Ge(Li)] diode gammaray detector. Also, in situ analysis of terrestrial and marine mineral deposits appears practical. Laboratory studies show that a 1- or 2-min exposure of mineral samples to the thermalized neutron flux from a 1-mg 252Cf source followed by a 1- or 2-min count with an 80-cm3 Ge(Li) diode will allow the measurement of most elements at concentrations of 10- to 100-fold below the levels of economic interest. The technology developed for laboratory mineral analysis is described and its applicability to in situ terrestrial and seabed mineral exploration is discussed.
