A calibration procedure for beta-gamma coincidence detector-systems using four radioxenon spikes

Appl Radiat Isot. 2024 Mar;205:111186. doi: 10.1016/j.apradiso.2024.111186. Epub 2024 Jan 10.ABSTRACTThe determination of activity concentrations of the CTBT-relevant radioxenon relies on a robust calibration method. A procedure is outlined using four radioxenon spikes for beta-gamma detector-systems with 4π geometry. Detection efficiencies of beta-gamma coincidences in the net count calculation method, including the interference matrix between radioxenon and radon, are determined by three measurement channels: beta singles, gamma singles and beta-gamma coincidences, without reference activity values.PMID:38224647 | DOI:10.1016/j.apradiso.2024.111186
