A NaI(Tl)-based radioactive noble-gas monitoring system used for radiation monitoring
Copyright © 2020 Elsevier Ltd. All rights reserved..
Radioactive noble-gas monitoring is necessary in nuclear facilities. A NaI(Tl)-based radioactive noble-gas monitoring system was developed. In order to increase the amount of air to be measured, the sample vessel of this system was larger than that of other systems, and was pressurized to about 5 × 105 Pa. In a laboratory experiment, technical ways to reduce the memory effect were investigated. In field tests, a method of spectra analysis was established and calibration coefficients and minimum detectable concentrations of 133Xe, 135Xe and 41Ar were calculated. Finally, detection ability was compared with other online monitoring systems.
