| 520 | $aThe principal objective of this study was to determine the minimum protection factor that could be applied to the annual average ambient airborne radioactivity concentration for a separation plant worker following periods of intermittent respiratory protective equipment (RPE) usage. The study was designed to measure the program protection factor of the half-mask filter cartridge respirators used in the plant | ||
