某部营区深井内有一个钴源,原作科研实验用,因铜质盛源架锈蚀,放射源已无法从管中取出送废源库处理。为了防止该源丢失、泄漏,保障周围人员安全和环境不受污染,我们采取了就地水泥封固存放方法,达到了安全有效目的。现报告如下。1 材料与方法1.1 废源简介 该废源位于深0.4m、长1.8m、宽1.4m的井底。井底厚O.5m,进壁厚0.25m.均为钢筋混凝土结构。该源放射性活度为22.6TBq(613ci),被加工成21根15×90mm的钴棒1.2 封存方法及程序 ①封存原理:参照文献。
One of the battalion deep wells has a cobalt source, which was originally used for scientific experiments. Due to the rusting of the copper Shengyuan frame, the radioactive source can not be taken out of the pipe and sent to the source warehouse for disposal. In order to prevent the loss of the source, leakage, to protect the safety of the surrounding people and the environment from pollution, we have adopted a method of cement storage in situ, to achieve a safe and effective purpose. The report is as follows. 1 Materials and Methods 1.1 Introduction to Waste Sources The waste source is located at a depth of 0.4m, a length of 1.8m and a width of 1.4m. Bottom thickness O.5m, into the wall thickness 0.25m. Are reinforced concrete structures. The source radioactivity 22.6TBq (613ci), was processed into 21 15 × 90mm cobalt rod 1.2 Sealing methods and procedures ① Sealing principle: reference literature.
