ABSTRACT:
A monitor for detecting airborne radioactive particulates is disclosed. An elongate strip of filter paper is fed across first and second air inlet ports of a collection chamber. Ambient air is selectively drawn into the chamber through a selected one of the inlet ports and out an through outlet port. Particulates trapped on an area of the filter paper in alignment with the open inlet port are detected after advancing the strip area into alignment with the closed inlet port. A radiation detector mounted on a movable arm is selectively positioned over the closed inlet port to detect the trapped radioactive particulates, while a new sample is collected at the open inlet port. Exposure of the detector surface to corrosive materials is avoided and the detector can be positioned close to the filter strip to maximize counting efficiency and energy resolution. A microprocessor controls the functions of the monitor and allows continuous unattended operation.
