摘　　要：本文描述用同位素稀释质谱法测定反应堆辐照元件中^(149)Sm和^(150)Sm含量的方法步骤,研究了^(149)Sm、^(150)Sm沿反应堆元件的轴向分布规律。The determination of nuclide ^(149)Sm and ^(150)Sm in irradiation element of nuclear reactor by IDMS is described. The axial distribution curves of nuclide ^(149)Sm and ^(150)Sm along the irradiation element are given. The error of determination is less than ±0.6%.
