Digital coincidence counting with 4 πβ(PPC)-γ for the standardization of < sup > 60 < /sup > Co

Appl Radiat Isot. 2024 Mar;205:111173. doi: 10.1016/j.apradiso.2024.111173. Epub 2024 Jan 3.ABSTRACTA 4πβ(PPC)-γ coincidence system has been made at KRISS based on a digital DAQ. 60Co sources were measured to verify the system. The maximum detection efficiency for beta particles was estimated to be 96.7 %. Massic activities for sample sources had 0.005 % of the sample variability error, which was well within the expanded standard uncertainty of 0.54 % (k = 2).PMID:38211394 | DOI:10.1016/j.apradiso.2024.111173
