FJ-HF11 Hand and Foot α,β Pollution Monitor
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.
Application areas
Radionuclide laboratory;
Nuclear fuel plant;
Environmental surveying, national security;
nuclear medicine;
PET equipment.
Features
The 10-inch touchscreen color display makes it easy to operate.
Intelligent operation with self-diagnosis function;
The hand detector can be easily detached and used for measuring key areas of the body;
The personnel location sensor can indicate the accurate location and provide voice prompts to guide the measurement.
It uses a touch screen, allowing healthcare personnel to operate it independently, while the person being examined does not need to perform any operation, making it convenient to use;
Radiation measurement parameter setting, status indication, and voice alarm functions;
Local data storage, query, and dynamic display functions;
It has a self-diagnostic function, and self-test items include: hand infrared detection and foot infrared detection;
When the measurement result is contaminated, a voice prompt, a text prompt, the location of the contamination, and the measurement result will be provided.
