New xenon gamma-ray spectrometer for sorting of radioactive waste

摘要

A gamma-ray spectrometer for radioactive waste sorting is presented. The equipment is based on a new "thin-walled" xenon gamma-ray detector with sensitive volume of 4 liters and a digital electronics unit. Use of the thin wall (0.5 mm of stainless steel covered with fiberglass) provides lower absorption of gamma-rays by the detector's walls and expansion of the energy range of radiation being registered. The digital electronics unit makes it possible to use the equipment in unfavorable field conditions such as high levels of acoustic influence.
