This paper presents the principles and calculation methods in design of shielding doors for an electron accelerator with maximum energy of 2.2 MeV and maximum beam intensity of 25 mA. The steel slab needed for shielding door of radiation hall was calculated of 12 cm in thickness. And several thickness values for shielding door of accelerator hall were provided to accommodate different beam losses. To facilitate casting, the two doors were both built with steel slabs of 20 cm in thickness. Under full power...

This paper presents the principles and calculation methods in design of shielding doors for an electron accelerator with maximum energy of 2.2 MeV and maximum beam intensity of 25 mA. The steel slab needed for shielding door of radiation hall was calculated of 12 cm in thickness. And several thickness values for shielding door of accelerator hall were provided to accommodate different beam losses. To facilitate casting, the two doors were both built with steel slabs of 20 cm in thickness. Under full power operation of the accelerator, the exposure rate by the shielding doors outside the halls were measured as follows: 4.1×10 -9 C·kg -1 ·h -1 by the lower edge of the shielding door of accelerator hall; 11.6×10 -9 C·kg -1 ·h -1 by the lower middle edge of the shielding door of radiation hall and 10.6×10 -9 C·kg -1 ·h -1 by its lower lateral edges.

本文简要介绍一台电子能量为2.2MeV、束流强度为25mA的电子辐照加速器的辐射防护设计。其主要内容是防护门设计中考虑的原则和计算方法。最后给出的计算结果是:辐照室防护门为12cm铁;加速器室防护门算了几个结果,供加速器人员根据束流损失情况进行选择。建造时,为了加工方便,两个防护门均铸造为厚20cm铁门。建成后,在满功率运行状态下进行了实测,结果为在未扣除天然本底的情况下,加速器室铁门下门缝处的照射量率为4.1×10-9Ckg-1h-1(16μR/h);辐照室铁门中缝下沿为11.6×10-9Ckg-1h-1(45μR/h),边缝下沿为10.6×10-9Ckg-1h-1(41μR/h)。
