FJ-HF11 Hand and Foot α、β Pollution Monitor
Product Overview
This instrument is primarily used in nuclear power plants, nuclear facilities, and mining sites to measure alpha and beta contamination on the hands, feet, and clothing surfaces of researchers and workers handling radioactive materials. When detected radiation levels exceed preset thresholds, the instrument issues alarms to ensure personnel safety and prevent internal radiation exposure.
Application Areas
- Radionuclide laboratories
- Nuclear fuel plants
- Environmental surveying and national security
- Nuclear medicine facilities
- PET equipment installations
