切尔诺贝利事故使建立国际一致的方法以计算释入环境的放射性核素对公众成员所致剂量的问题显得更加必要.所以,国际放射防护委员会(ICRP)1987年5月在第二委员会中设立了一个工作组,以确定公众摄入重要放射性核素单位活度后受剂量的年龄依赖关系(即剂量换算系数).最近发表的第一部分报告给出了氚水、有机结合氚(O-BT)、~(14)C、Sr、Zr、Nb、Ru、I、Cs、Ce、Pu、Am、Np等放射性核素摄入和吸入后的剂量换算系数.为了提供公众摄入后的代表值,给出了不同年龄(3个月、1、5、10、15岁儿童和20岁成年人)人员摄入后至70岁所受剂量.
The Chernobyl accident made it even more necessary to establish an internationally agreed method of calculating the amount of radionuclides released into the environment to the members of the public, so that the International Commission on Radiological Protection (ICRP) Set up a working group to determine the dose-dependent age dependency (ie, dose conversion factor) of the public after exposure to vital radionuclide activity. The first part of the most recent report, entitled Tritiated Water, Organic Tritium (O Dose conversion factors for uptake and inhalation of radionuclides such as ~ (14) C, Sr, Zr, Nb, Ru, I, Cs, Ce, Pu, Am, Np, etc. In order to provide a The representative values give the doses taken up to 70 years of age by persons of different ages (3 months, 1,5,10,15 and 20 years of age).
