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.”

A prototype of a tritium transfer model in the environment was developed for the purpose of dose estimation in our institute in 1995. The model consists of many compartments representing tritium reservoirs in a hydrological cycle in the local hydrosphere, and reservoirs in food chains in the aquatic and terrestrial environments. Underground tritium reservoirs are defined as three aquifers in the model, although the number of aquifers might depend on the site. Our present work was focused on an application of the model to an area with nuclear facilities, Tokai-mura, Japan, where there is only one aquifer. The Shinkawa (Shin River) flows through the Muramatsu area between two nuclear facilities, and then into the Pacific Ocean. About 2000 people live in the area and some use groundwater as a convenient daily water source as well as village tap water. Samples at 16 rainwater and 20 groundwater sites from the Muramatsu area (5 km2) as well as 3 groundwater sites from an inland area were taken during 1983–90, and tritium concentrations were measured. In order to investigate the scale of the drainage system of the Shinkawa basin, time series data of excess tritium in rainwater and groundwater were applied to our transfer model. As a result, the volume of the aquifer was calculated as half of the annual rainfall in the area. This is so small that the tritium concentration of the groundwater has a quick time trend response to input of tritium from rainwater. The results can be used to estimate population dose of the residents in the Muramatsu area.
