Gamma-ray spectrometer "ATOLL-1M"
|
Purpose:
registration of gamma-ray spectra and identification of radionuclides;
measuring radionuclide activity in building materials, mineral raw materials, waste products, food stuff and other materials in the Vessel Marinelli geometry.
The gamma-ray spectrometer "ATOLL-1M" can operate both in laboratory conditions (with low- background protection) and in field conditions. The instrument has an effective system of thermal compensation.
