目前,放射治疗仍为治疗肿瘤的较为重要的手段之一。对于钴机房的防护方面,由于国内尚少这方面的经验介绍,而我们自己在这方面是有教训的,因此将有关资料整理如下,以供参考。为了降低放射线对工作人员及邻近人群的伤害,除钴治疗机本身的防护壳以外,还要使用防护墙来屏蔽射线。因此在建造医用钴治疗室时,必涉及到防护墙厚度的计 At present, radiation therapy is still one of the more important methods for treating tumors. As for the protection of the cobalt machine room, as China has yet to introduce experience in this area, and we ourselves have lessons in this regard, the relevant data will be compiled as follows for reference. In order to reduce the radiation damage to workers and neighboring people, in addition to the protective shell of the cobalt treatment machine itself, a protective wall is also used to shield the rays. Therefore, when building a medical cobalt treatment room, the thickness of the protective wall must be involved.
