G390 Whole Body Gamma Contamination Monitor

Product Description

G390 Whole Body Gamma Contamination Monitor (gate C1) is a device developed and designed by shuoboda for the detection of whole body gamma contamination of personnel at the exit of a radioactive sanitary pathway in a nuclear power plant or related nuclear facility. The instrument uses a large area high performance plastic scintillator detector with an original blind spot free detector design method, which can monitor the whole body gamma radioactive contamination and indicate the location of contamination.
