CN-101 60Co放射源研制

介绍了CN-101型工业辐照用⁶⁰Co密封源的研制过程和产品制备的工艺流程，包括结构设计、原型源试验、钴棒束水下解体、钴棒水下活度测量、钴棒热室切割、封装焊接、泄漏检查、表面污染检查、外形尺寸检查、最终产品活度测量。2011年2月产品通过合格性鉴定，结果表明，产品各项技术指标达到国际先进水平。CN-101密封源的研制成功填补了国内辐照加工业空白，打破了国外产品的垄断，年生产能力达2.035×10¹⁷ Bq。

Development of CN-101 60Co Radioactive Source

The paper introduced the development and process of CN-101 ⁶⁰Co sealed source for industrial irradiation, including the structure design, prototype test, under-water disassembly of cobalt bundles, underwater activity measurement of cobalt rods, cutting of cobalt rods, encapsulation and welding of capsules, leakage test, surface contamination test, outside dimension measurement, and activity measurement of the finished sources. The products passed through certification test in February 2011, and the results show that all technical parameters reach the advanced world level. The successful development of CN-101 sealed source fills the vacancy of domestic fields and breaks with the monopoly of foreign products. Annual fabrication capacity can reach to 2.035×10¹⁷ Bq.
