1．85×10 1PBq钴－60辐照室主要结构参数的设计计算

The design and calculation of the parameters of the main structure for 1. 85× 10￣1PB_q cobalt-60 ra-diation cave.

利用减弱倍数法和累积系数法分别计算了浙江农业大学辐照中心１．８５×１０￣１ＰＢ＿ｑ钴－６０辐照室混凝土主防护墙厚度和贮源水井深度，并对迷道长度和外防护墙厚度进行了估算。

The methods of multiplication decreasing and accumulative factor are applied to calcu-lation the thickness of concrete inner protective wall and the depth of well for storing radiationsource,respectivily. The length of mazy road and thickness of outer protective wall was also esti-nated.
