Open publisher page 2 citations

Abstract

Abstrcat A 4πβ+4πγ equipment for radioactivity measurement is made up of a 4π flow-gas proportional counter, a well-type NaI(Tl) detector and a HPGe detector. We place the 4πβ counter onto the HPGe detector and into the well of NaI(Tl) detector for carrying out the measurement of β-ray detection efficiency, radioactivity and γ-ray emission probability all the time. The radioactivity of ()~(60)Co, ()~(134)Cs and (()~(166m)Ho) were determined by 4πβ+4πγ method for radioactivity measurement, the result was 127.64(1±0.34%)Bq/mg for ()~(60)Co,191.68(1±0.27%) Bq/mg for ()~(134)Cs and 130.17(1±0.21%)Bq/mg for ()~(166m)Ho , which were well agreed with the results of native or national compared measurement. And the mainγ-ray emission probability of ()~(134)Cs and ()~(166m)Ho were also detemined and the results were accorded with the literature in uncertainty.
