Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

Calculations have been carried out to obtain the time and spatial dependence of the long-lived induced activity in soil produced by 200-MeV protons incident on a small cylinder of graphite buried in soil. Only radioactive nuclei with halflives greater than or equal to that of 7Be (0.147 year) were considered. Monte Carlo methods were applied to determine the induced neutron flux which was combined with both calculated and experimental radiochemical cross sections to determine the rate of residual-nuclei production. Through the use of the results of the calculations, a procedure has been established whereby the approximate contribution of each target nucleus to the production of a particular radioactive nucleus can be obtained. The results of the calculations are also used to approximate the long-lived induced activity in soil when the small cylinder of graphite is embedded first in another material, such as iron, which is in turn surrounded by soil.
