Spectrometer-dosimeter of gamma-radiation "Rhythm-S"
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 Marinelli geometry (without transferring to a laboratory);
quick measuring of radionuclide activity in the "2π" geometry (without sampling);
As a dosimeter, the device is designed for:
detection of gamma-ray sources and radiation-contaminated materials;
monitoring of transport vehicles crossing national borders;
monitoring of radioactive contamination in scrap metal;
measuring gamma-exposure rate in the field and in production environment.
