Gamma beta and alpha spectrometer - radiometer MKGB-01 RADEK

Purpose

Spectrometer – radiometer of gamma-, beta- and alpha - radiation MKGB-01 RADEK is intended for measuring energy distribution of the gamma and beta radiation, and activity of gamma-, beta- and alpha-emitting radionuclides.
The spectrometer is stationary measurement instrument and is designed for use in the laboratory. The spectrometer is used to measure the activity (specific activity) natural radionuclides 226Ra, 232Th, 40K,222Rn, and artificial radionuclides (137Cs, 90Sr-90Y, etc.) in the soil samples, rocks, vegetation, water, food , building materials, chemical industry materials, alloys, scrap metal and other technology products. Also is used for measuring beta- and alpha- emitting radionuclides in food, biological samples and other materials.
