摘　　要：采用 Li F薄膜和 Ca F2 :Mn剂量片 ,对以90 Sr- 90 Y作为辐射源的半导体辐照效应模拟装置中的剂量进行了实验测量 ,并用经验公式计算了相应的辐射剂量场分布。实验测量和理论计算数据之间的偏差分析结果表明 ,用 L i F薄膜测量90 Sr- 90The 90 Sr 90 Y Source is used as the radiation source installed in an apparatus simulating ionizing radiation effects. The radiation dose field distribution is measured by using TLD dosimeters LiF film. And it also is calculated theoretically. The measurement accuracy has been improved. The analysis of measuremental results and theoretical calculation shows that this method is feasible. (
