HFM100 Hand and Foot Surface Contamination Monitor α/β Nuclear Radiation Contamination Detector
HFM100 Hand and Foot Surface Contamination Monitor α/β Nuclear Radiation Contamination Detector
HFM100 hand and foot surface contamination monitor (α/β type and β type) is mainly used in nuclear power plants or related nuclear facilities on the radioactive control channel, from the control area of the hands and feet of the staff surface pollution monitoring, through the analysis of data to timely discover the potential accident, in order to timely detect pollution and prevent pollution transfer. It is one of the means to ensure safe production in nuclear power plants or related nuclear facilities and other radioisotope application departments, and can also be used in other radioisotope application departments.
