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. (
