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 137 Cs irradiation unit of the Atomic Energy Agency of Zhejiang Academy of Agricultural Sciences was built in 1981 with an activity of 2.146 × 101-15 Bq and a radioactive source diameter of 5.2 cm and a length of 48 cm. The source is housed in a double stainless steel casing filled with helium gas. Yan source has a good positioning repeatability, multiple sources of radiation dose rate relative deviation of 0.39%, 1m equivalent amount of line uniformity better than 1.02. Radiation breeding, radiation disinfection and sterilization of medical supplies and irradiation disinfection of traditional Chinese medicine were carried out using ~ (137) Cs irradiation equipment.
