A, B, Gamma and_Multifunctional Radiometer/Radiometer
It provides you with a fast, accurate and convenient means of radiation detection. It can be used not only for radiation dose rate detection but also for surface contamination measurement. This product adopts GM detection method to monitor radioactive workplaces and surfaces. It is a high cost-effective radiation for measuring alpha, beta, gamma and X radiation contamination counts and environmental dose rate of laboratory workplaces, floors, walls, hands, clothes and shoes. Radiometric instruments. Commonly used for:
1. Check local radiation leakage and contamination.
2. Check the radon radiation in the surrounding environment;
3. Check the radioactivity of stone and other building materials;
4. Check landfills and garbage dumps with nuclear radiation risk;
5. Measure the X-ray radiation intensity of X-ray instruments from medical to industrial use.
6. Check the pollution of radium in groundwater;
7. Check the radioactivity of underground drilling pipes and equipment;
8. Monitoring air and water pollution around nuclear reactors;
9. Check the harmful radiation of personal valuable property and jewelry;
10. Check the radioactivity of porcelain, tableware, glass, etc.
11. Accurate location of radiation sources;
12. Home decoration inspection.
