Whole body spectrometer SEG-10P (whole body counter)

The whole body spectrometer SEG-10P “RADEK” (whole body counter, WBC) in configuration with two detectors BDEG-80 (or one BDEG-150) and one detector BDEG-25 is intended for measuring the incorporated gamma-radiating radionuclides content in whole human body, in human lungs and in human thyroid.
For the calibration of the spectrometer is used whole body phantom UP-02T ("IGOR") or ARDF-10 "ROMAN".

Features
