Gamma spectroscopy monitor of noble gases

The device is intended for gamma spectrometric activity measurement of rare gases in nuclear power facilities exhausts.

Sampling proceeds via a bypass and a compressor, that pumps the required amount of a sample through an aerosol filter and an iodine filter to a Marinelli beaker. The semiconductor detector and measuring vessel are shielded with low-background lead.

Results are saved to PC summarised, and displayed as 1 hour and 24 hour spectra. The system identifies the individual radionuclides and gross activity volume in the measured air mass.


Energy range: 50-2000 keV
Detector type: HPGe
