OPERATING PRINCIPLE
 
Spectrometers are composed of an external spectrometric gamma radiation detection unit and a processing unit.
 
Highly-sensible scintillation NaI(Tl) detectors are used for measurement of gamma radiation energy distribution, ambient gamma radiation dose rate equivalent, search and identification of radionuclides.
 
Geiger-Muller counter tube, integrated into the processing unit, is used to extend the range of ambient gamma radiation dose rate measurement as well as to monitor radiation level around the operator.
 
External detection units can be connected to the spectrometer to measure alpha and beta particles flux density of contaminated surfaces.
