title: Design of an airborne plutonium survey program for personnel protection.
abstract: Various options were considered for surveying and real-time monitoring for airborne plutonium for optimum protection of personnel. Placement of samplers, dilution factors, and analysis time were considered in the strategy for achieving regulatory compliance and maintaining internal dose as low as reasonably achievable (ALARA). It was found that protection was relatively insensitive to placement as was sensitivity of detection. It was also found that maximum protection was obtained with few detectors and increasing the number of detectors above the optimum value did not appreciably increase the information about a release nor did it aid in locating the release. It was determined that the best protection was obtained with alarming monitors if the detection sensitivity was sufficiently low. Integrating samplers requiring laboratory analysis can be more sensitive than alarming monitors, but the lack of timeliness limits the amount of protection. The integrating samplers can be used effectively to monitor engineering controls. Personal air samplers also offer little protection but can be very effective in analyzing exposure by craft and job type.
