Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

The photofraction, i.e., the fraction of incident photons absorbed, and the Compton electron distribution of a very large NaI(Tl) scintillator are investigated. They are estimated from the measurement of energy spectrum of photons backscattered from the front face of a scintillator that is nearly semi-infinite for 60Co and 137Cs gamma rays. The estimated photofraction was 0.79 for 60Co gamma rays and 0.85 for 137Cs gamma rays. The Compton electron distribution obtained was compared with the results of Monte Carlo calculations. They show fairly good agreement.
