Environmental Surveys:
In addition to periodic radiation surveys using hand-held instruments, environmental monitoring is accomplished using radiation dosimeter badges. Areas monitored are located around the exterior of the Reactor Building (RB) and nearby buildings, including the Nuclear Sciences Building (NSB), the Rhines Hall (RH), Weil Hall (WH), Weimer Hall (WmH), and Wertheim Engineering Lab (WEL). The environmental dosimeter reports are tabulated and presented in Table III. Dose equivalents below the minimum measurable quantity are reported as "M".
