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 applicability of bremsstrahlung counting to in-situ measurements of high level tritiated water has been examined. A specially designed metallic vial fitted with a gold-coated beryllium window was prepared for the present examinations. Only tritiated water of a given amount was put into the vial. The volume dependence of the X-ray intensity showed that 5 cm3 of tritiated water is sufficient for measurements. It was found that the spectrum of X-rays induced by -rays consisted of only bremsstrahlung. The bremsstrahlung spectrum could be reproduced quite well by computational simulation. A good linear relation between the X-ray intensity and tritium concentration was obtained in the concentration range of 4 × 10-3-40 MBq cm-3. Furthermore, effect of nickel added as a model impurity to tritiated water was examined, and it was found that the tritium concentration can be evaluated from the X-ray intensity without any correction in the presence of impurity below 200 ppm.
