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 thickness of the main protective wall of 1.85 × 10 ~ 1PB_q cobalt-60 irradiation chamber concrete and the depth of reservoirs were calculated by the method of attenuation multiplier and cumulative coefficient respectively. The effects of the length of confusion and the outer protective wall Thickness was estimated.
