摘要
根据最新资料，在按放射性核素在肺部吸收速度和物态分类对 １ ４３５ 个核素次所做的毒性分组的基础上，根据我国《电离辐射防护和辐射源安全基本标准》编制组的要求，经合并处理，得到了 ８５１ 个放射性核素毒性分组清单。本文将此清单与拟被取代的 Ｇ Ｂ ４７９２ 和 Ｇ Ｂ ８７０３ 两标准的相应内容做了比较，总体上仍是相近的，部分差异来源于剂量限值和剂量转换系数的变化。
The toxicities of 1 435 radionuclides , in respect to the lung absorption speed and physical state, were reclassified on the base of updated data. Then the toxicity reclassification of 851 radionuclides was listed by the combination according to the request for editing the State Standards entitled 《Basic Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources》. The list of new classification was compared with that of GB 4752 and GB 8703 and resulted to prove that all of them was similar as a whole,but some differences between them come from the changing of dose limits and dose conversion coefficients.
