AB335 Hand and Foot Surface Contamination Monitor

Product Description

AB335 Hand and Foot Surface Contamination Monitor is primarily used for safety testing of personnel in radioactive plants such as nuclear power plants, nuclear processing plants and nuclear waste warehouses etc. The instrument focusing on the presence of radioactive contamination on the surfaces of key parts of personnel such as hands, feet and clothing. When alpha and beta rays are detected on the surface of key parts of the person's hands, feet and clothing exceeding the threshold, the instrument issues an alarm and indicates the degree of contamination of the hands, wrists, feet and clothing to ensure that the personnel leave without contamination.
