摘　　要：浙江省农科院原子能所的^（１３７）Ｃｓ辐照装置于１９８１年建成，活度为２．１４６×１０１^（１５）Ｂｑ，放射源直径５．２ｃｍ；长４８ｃｍ。该源封装在双层不锈钢套壳内，套壳之间充满氦气。艳源具有良好的定位重复性，多次提源照射量率的相对偏差为０．３９％，１ｍ同等量线上的均匀度优于１．０２。利用^（１３７）Ｃｓ辐照装置开展了辐射育种、医疗用品的辐射消毒灭菌、中成药的辐照消毒等方面的研究工作。The 137Cs radiation set.whose radioactivity was 2.146 x 10￣(15)Bq,It was built in 1981 in institute for Application of Atomic Energy.Zhejiang Academy of Agricultural Sciences. The is7Cs source was sealed in stainless steel tube filled in helium. The effective diameter of radioactive area is 5.2 cm and its length is 48 cm.The set has a good repeating for fixed location,the relative divation of dose rate is 0. 39, and the dose even rate is superior to 1.02.The 137Cs radiation set was used to study plant breeding.irradiation of food,radiosterilization of medical product and drugs, and so on.
