We conducted a basic performance study of the “beta-panel for whole body survey”, a new device for the test of body surface contamination. This equipment is installed in a small number of units, and performance evaluation by users has not yet been done. Five items were examined: sensitivity differences between detectors, the effect of using anti-contamination film, the effect of room temperature, the effect of distance from the detector on measured values, and sensitivity to contamination in the frame area without detectors. We generally obtained good results in terms of sensitivity differences. Although some points require attention in the actual inspection, for instance, position where the subject is standing and contamination in the frame area, the beta-panel can shorten contamination tests, so useful in the event of a nuclear disaster.
