FJ-HF11 High Sensitivity Nuclear Pollution Monitor Alpha Beta Radiation Detection for Nuclear Power Plant
Product Introduction
This product is mainly used in nuclear power plants, nuclear facilities, and mining sites. It is used to measure the alpha and beta contamination on the hands, feet, and clothing surfaces of researchers and workers handling radioactive materials. When the alpha and beta radiation detected on the hands, feet, and clothing surfaces exceeds the threshold, the instrument will issue an alarm to ensure the personal safety of the staff and prevent internal radiation exposure.
