WCM1000 Whole Body Gamma Pollution Monitor
WCM1000 Whole Body Gamma Contamination Monitor
WCM1000 whole body gamma contamination monitor is installed at the health exit of the radiation control channel of nuclear power plant or related nuclear facility plant. It is used to monitor the gamma radiation contamination of all parts of the whole body of workers when they exit the radiation control zone, so as to detect the contamination in time and prevent the transfer of contamination. It is designed as a door cabinet structure with electric railings at the entrance and electric doors at the exit.
Its main functions are:
1. Inspection of the whole body pollution of staff and its level
2. Find out the beginning of the accident by analyzing the data in time.
3. Isolate control zones to avoid pollution diffusion in control zones
4. Avoid unauthorized removal of radioactive sources from the control area
Technical characteristics:
1. Plastic scintillator detector
2. Flat panel color display, showing the counting rate and total counting rate of each detector, indicating the polluted position.
3. Speech warning during measurement, light and voice alarm when polluted
4. The parameters of pollution measurement threshold and background measurement threshold of each detector can be adjusted by software.
5. Provide calibration source and source frame, and calibrate instrument by software.
6. Equipped with emergency channel button
7. Personnel Approaching Detector and Personnel Position Sensor
8. Timing background measurement and automatic background deduction
