Description

A 4πβ-4πγ detector configuration with a 4πβ(PC) flow proportional counter and a large size well-type 4πγ NaI(Tl) crystal was described, and the theoretic function of sum efficiency extrapolation was established. The radioactivities of 60Co and 134Cs source were measured using this sum extrapolation method, 0.29% and 0.19% relative uncertainty obtained for each, and the result was compared with the value of coincidence efficiency extrapolation. The analysis indicates this method is fit for measuring the activity of complex decay nuclides. (authors)
