摘要
放射性气溶胶的粒度分布数据是估算内照射剂量和评价吸入危害的基础资料。本文根据多年来对核工业中部分生产场所进行的放射性气溶胶监测,对从铀矿开采到燃料元件制造的各主要生产环节,总结报告了放射性气溶胶的粒度分布监测数据。这些数据包括活度中位空气动力学直径(AMAD)及其几何标准偏差(?)、α放射性浓度(C)。文中还给出了个人采样器和固定采样器监测结果的比较。
The data of particle size distribution of radioactive aerosols are furdamental for estimating in-ternal exposure and inhelation hazards.Based on the results of surveying radioactive aerosols in variousoperational fields of nuclear fuel cycle system from uranium mining through element manufacturing inpast years,these data were summed up in this report,including:1)Activity medium aerodynamic di-ameter(AMAD)and geometric standard deviation(σ(?)),and 2)α radioactivity concentration(C).Comparisons were also made between results obtained by personal samplers and location sampler.
