Development of a Room Air Monitor System and Workplace Transuranic Aerosol Measurement System

The design of the room air monitor consists of a filter medium housed in a separate fixture connected directly to a vacuum system. A 1700 mm2 detector is housed in front of the filter medium to detect the presence of alpha particles emitted from the material collected by the filter medium. Several versions of the system have been built and used in production areas at the Rocky Flats Plant. A Workplace Transuranic Aerosol Measurement System with improved sensitivity for stack monitoring is also reported. The tasks for the development of these two systems are listed, and cost estimates and tentative schedules are summarized. Drawings illustrating these systems are also given
