AT1125 and AT1125A Radiation Monitors
Portable high-sensitivity Radiation Monitors are designed to search for and detect sources of gamma radiation, measure ambient gamma radiation dose equivalent rate, alpha and beta particle flux density from flat contaminated surfaces, as well as for radiometric monitoring of radionuclides in samples using 0.5-litre Marinelli beaker.
For radiometric radionuclide content monitoring in samples the following Monitor design variants are possible:
1) 137Cs monitoring
2) 137Cs and 134Cs + 137Cs monitoring
3) 131I, 137Cs and 134Cs + 137Cs monitoring
