Basic study of equipment for body surface contamination test during contamination screening

Abstract

After Fukushima Daiichi Nuclear Power Plant Accident in 2011, a new device called “Beta Panel Σ” was released that can test for body surface contamination in designated areas. It can measure head, face, back of hands, palm of hands and shoe sole.

Since this device has not yet been widely used nationwide and has not been evaluated by users, we conducted a basic performance evaluation this time. As a matter of consideration, we investigated whether the measured values would be similar using background and radiation sources. As a result, it was found that there were no problems in using it, but it was also found that there were some points that needed to be taken care of.
