Referring to shortcomings of modern radiation detection and monitoring devices, an operable prototype of the device for determination of the gamma radiation exposure dose rate within the range from 10 μ R/h to 1000 R/h, with the energy γ -radiation sensitivity range from 50 keV to 3 MeV, has been offered. The prototype is able to register the α-radiation and β-radiation flux density. The device operates using two detection units and a two-channel counting unit. Registration of the exposure dose rate is provided by using CdTe detector, and registration of the α-radiation and β-radiation flux density is provided by using Si detector.
