七十年代以来中国的辐射工艺技术获得了迅速发展。现今遍布在北京、上海等３８个城市中，设计容量在３．７ＰＢｑ以上的‘’ＣＯ辐照装置约有５０套，其总装载容量已超过８６２ＰＢｑ。电子束辐照装置约２６套，其总功率已达到９２６ｋＷ。辐射工艺（或辐射加工）的效果与辐射剂量方法的合理应用及测试密切相关。剂量方法对于辐射工艺技术及其质量保证、质量控制的重要性在中国已被认识。为履行。中华人民共和国计量法，，１９９０年４月１８日国家科委与国家技术监督局联合发布。辐射加工计量监督管理暂行规定，。在此基础上已实施和正在起草的有关辐射加工的技术法规包括国家标准、计量技术规范、检定系统与检定规程等文件已达２０余种。为提高电子束和６０ＣＯγ射线的剂量测量的准确性，一级标准实验室（国家计量研究院）和二级标准实验室（上海计量技术所）建立了溯源的体系。在国家技术监督局的前身国家计量局的支持下已完成近１０种常规剂量计和传递剂量计及其测试装置。塑料膜剂量计的测试与应用也受到重视，今后将进一步完善电子束辐射的剂量测试，使我国剂量技术的水平持续地保持在国际水平的前沿。
Since the 1970s, China’s radiation technology has gained rapid development. Nowadays, there are about 50 sets of CO irradiators with a designed capacity of more than 3.7PBq in 38 cities such as Beijing and Shanghai, with a total loading capacity of over 862PBq. About 26 sets of electron beam irradiation device, the total power has reached 926kW. The effects of the radiation process (or radiation processing) are closely related to the proper application and testing of the radiation dose method. Dosage methods The importance of quality control for radiation technology and its quality assurance has been recognized in China. To fulfill. Metrology Law of the People’s Republic of China, April 18, 1990 jointly issued by the State Science and Technology Commission and the State Bureau of Technical Supervision. Interim Provisions on Supervision and Administration of Measurement of Radiation Processing. On this basis, more than 20 kinds of documents have been drafted on the technical regulations concerning radiation processing, including national standards, measurement specifications, verification systems and verification protocols. In order to improve the accuracy of dose measurement of electron beam and 60COγ-ray, a standard laboratory (National Institute of Metrology) and a secondary standard laboratory (Shanghai Institute of Metrology) established a traceability system. Nearly 10 kinds of routine dosimeters and delivery dosimeters and their test devices have been completed with the support of the State Metrology Bureau, the predecessor of the State Bureau of Technical Supervision. The testing and application of plastic film dosimeter have also received great attention. In the future, the dose testing of electron beam radiation will be further perfected to keep the level of dose technology in our country at the international level.
