The absolute measurement of radioactivity of ¹³³Ba which is an electron capture nu-clide was carried out by the β- γ coincidence counting method. The counting rates at the β-, γ , and coincidence-channels were measured using a 4πproportional counter and two Nal(Tl) scintillation detectors.
By the detection efficiency extrapolation varying low energy threshold levels, the mean result obtained was(185.2±0.7) kBq/g of specifice radioactivity at the reference time(OOh, September 1, 1991).
