【摘要】：目的分析2010—2014年我国放射性同位素的进出口情况,促进辐射安全监督管理更加合理、有效、科学。方法通过"国家核技术利用辐射安全管理系统"收集相关资料,分别对2010—2014年我国放射源和非密封放射性物质的进出口情况进行分析。结果 2010—2014年,我国每年进口铯-137、钴-60、镅-241和铱-192等20多种放射源,总量29 521枚,其中铯-137源(7 084枚)和钴-60源(6 409枚)进口量位居前二位(分别占24.00%和21.71%);非密封放射性物质主要涉及铱-192、钴-60以及硒-75等核素;放射性药品中钼-99(锝-99m)的进口量最大(占63.02%),其次为碘-131(占33.34%)和碘-125(占3.15%)。出口的放射源涉及铯-137、钴-60、镅-241以及氪-85等10多种核素,类别从Ⅰ到Ⅴ类全覆盖,出口总数达800多枚。结论我国生产高活度钴-60辐照源能力逐步提升,国内放射性药品的需求以及生产水平也逐步提升。
[Abstract]:Objective to analyze the import and export of radioisotopes in China from 2010 to 2014, and to promote the radiation safety supervision and management to be more reasonable, effective and scientific. Methods the import and export of radioactive sources and unsealed radioactive materials in China from 2010 to 2014 were analyzed by collecting relevant data from the National Nuclear Technology radiation Safety Management system. Results from 2010 to 2014, China imported more than 20 radioactive sources, including cesium 137, cobalt 60, americium 241 and iridium 192, with a total of 29,521. Among them, 7,084 caesium-137 and 6,409 cobalt-60 sources (24.00% and 21.71%, respectively) were imported, and the unsealed radioactive materials were mainly related to iridium-1922, cobalt-60 and selenium-75, etc. Among the radioactive drugs, the import of molybdenum (technetium-99m) was the largest (63.02%), followed by iodine 131 (33.34m) and iodine 125 (3.15%). More than 10 radionuclides such as cesium-137, cobalt-60, americium-241 and krypton-85 were exported. Conclusion the production capacity of high activity cobalt-60 irradiation source in China has been gradually improved, and the domestic demand and production level of radioactive drugs have also been gradually improved.
