An international exercise, registered as EUROMET project no. 907, was launched to measure both the activity of a solution of (124)Sb and the photon emission intensities of its decay. The same solution was sent by LNE-LNHB to eight participating laboratories. In order to identify possible biases, the participants were asked to use all possible activity measurement methods available in their laboratory and then to determine their reference value for comparison. Thus, measurement results from 4pibeta-gamma coincidence/anti-coincidence counting, CIEMAT/NIST liquid-scintillation counting, 4pigamma counting with well-type ionization chambers and well-type crystal detectors were given. The results are compared and show a maximum discrepancy of about 1.6%: possible explanations are proposed.
一项注册为欧盟计量研究计划（EUROMET）第907号项目的国际实验启动，旨在测量（124）Sb溶液的活度及其衰变的光子发射强度。LNE-LNHB将同一溶液发送给了八个参与实验室。为了识别可能存在的偏差，要求参与者使用其实验室中所有可用的活度测量方法，然后确定用于比较的参考值。因此，给出了4πβ-γ符合/反符合计数、CIEMAT/NIST液体闪烁计数、使用井型电离室和井型晶体探测器进行的4πγ计数的测量结果。对结果进行了比较，显示最大差异约为1.6%，并提出了可能的解释。
