The set of individual dosimeters "DP-22-B" and "DP-24" was produced presumably since 1971. The DP-22-B kit includes 50 DKP-50 dosimeters and a ZD-5 charger. The set of individual dosimeters "DP-24" contains 5 dosimeters DKP-50 and a charger ЗД-5. The DKP-50A type dosimeter allows measurements of individual exposure doses of gamma radiation in the range from 0 to 50P at an exposure dose rate of 0.5 to 200 R / h in the energy range from 100 keV to 2 MeV. To ensure greater convenience of use, the dosimeter is made in the form of a pen. The measured doses are counted on a scale located inside the dosimeter and calibrated in x-rays. The scale and thread of the dosimeter should have a clearly visible image. The dosimeter is charged from a splash-proof charger such as ZD-5. Food ZD-5 is carried out from batteries. Measurement range: 0 ... 50 R. Gamma radiation energy range: 0.1 ... 2 MeV. The basic measurement error is ± 10%. Dimensions of the set DP-22-B - 360x152x180 mm. Weight in packing - 5.5 kg.
