越来越多的退役放射源对环境造成了很大的压力,对可再利用密封放射源的回收再利用也越来越得到有关部门的重视。本文介绍了我国目前使用的常见密封放射源种类、拥有数量情况,退役或闲置密封放射源的处置及回收再利用现状;并分别就可回收再利用的退役60Co远距离治疗源、137Cs工业辐射源、60Co伽马刀治疗源在本公司再利用的现状,对不能再利用的密封放射源整备收储做了简单介绍;同时针对在退役密封放射源回收再利用领域存在的问题提出建议。

Under the stress of environment safety, more attention of the reuse of spent radioactive sealed sources has been paid by the government. The sorts and quantity of commonuse radioactive sealed source, the disposing status of spent sealed source were described. The reuse technique and status of spent ^60Co tele-therapy source, γ-knife source and ^137Cs radiation source, the conditioning and interim storage of the worthless spent source were introduced. The existing problems in the disposing of spent radioactive sealed sources were simultaneously discussed.
