AB333 Whole Body Surface Alpha and Beta Contamination Monitor

Product Description

AB333 Whole Body Surface Alpha and Beta Contamination Monitor (gate C2) is installed at the sanitary access exit of the radioactive control area of a nuclear power plant or related nuclear facility to monitor the possible contamination of all parts of the body of staff leaving the control area When the user-set alarm threshold is exceeded, the instrument will generate an audible and visual alarm and display the contamination location on the LCD screen, allowing for timely detection and prevention of contamination transfer. lt can be widely used in the sanitary access exits of the nuclear plants, nuclear facilities, nuclear power plants.

Functional features
