Activity measurement of mixed complex radionuclide like < sup > 152 < /sup > Eu with different methods

Appl Radiat Isot. 2022 Apr 7;185:110228. doi: 10.1016/j.apradiso.2022.110228. Online ahead of print.ABSTRACT152Eu has been standardized by three independent 4π β-γ coincidence counting systems with beta detectors as proportional counter, plastic scintillator and liquid scintillator along with the CIEMAT/NIST method. The average activity concentration by primary methods was linked to key comparison reference value (KCRV) by comparing it with that of 4π γ ionization chamber (GIC) whose calibration factor was determined from the KCRV (BIPM.RI(II)-K1.Eu-152 and CCRI(II)-K2.Eu-152) and deviates from GIC by ± 0.16% indicating good agreement within standard uncertainties.PMID:35421808 | DOI:10.1016/j.apradiso.2022.110228
