^(153)Sm、^(188)Re、^(89)Sr活度绝对测量比对

Absolute Radioactivity Measurements of ^(153)Sm, ^(188)Re and ^(89)Sr and National Comparisons

153Sm(T1 2=46.27h)和188Re(T1 2=16.98h)为短半衰期多γ射线源,89Sr为纯β核素,它们在核医学临床上的应用越来越广泛。本实验室参与了153Sm、188Re、89Sr活度测量的国内比对,使用4πβ γ符合测量标准装置对153Sm、188Re、89Sr样品进行了活度绝对测量。本实验室的测量结果与比对结果平均值在不确定度范围内一致。

153Sm and 188Re are short half-life nuclides and 89Sr is one of pure β-decay nuclide, these nuclides have being applied to nuclear medicine. It's very important to carry out comparisons for radioactivity standardization of these nuclides. Several laboratories in China including our laboratory took part in the comparisons. The results from our laboratory are in good agreement with the mean values.
