~(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

  • 摘要: 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。
