摘　　要：辐照技术的应用日益广泛 ,辐射源的退役也越来越受到关注。苏南某单位辐照室建立于 2 0世纪 80年代初 ,2 0 0 1年 4月对最早投入运营的 39根钴源进行退役 ,退役过程分三个阶段 ,历时 4 8小时。由于经过了精心的准备 ,采取了有效的防护措施 ,退役过程没有出现工作人员受超剂量照射的情况。Radiation technology has found an increasingly wide utilization in many fields, and more and more attention has been paid to the decommissioning of cobalt sources. In south Jiangsu, a radiation equipment was established in early 1980′s. The first 39 cobalt sources that were put into use were decommissioned in April, 2001. The decommissioning process, which lasted 48 hours, consists 3 phases. Because of elaborate preparation and effective radiation protection, there were not excess radiation exposures to the workers in the process. (
