摘　　要：本文采用倒推法,从放射性金属再利用最终产品所遵从的照射剂量率约束值出发,确定了熔炼后中间产品中的放射性核素活度浓度限值,最后推导出了熔炼厂接收放射性金属废物的表面剂量率限值(简称:表面剂量率接收限值)。表面剂量率满足该限值的废金属,再利用得到的最终产品满足规定的照射剂量率要求。By the inverse method,starting from the restrictive radiation dose rate followed by the final product reusing nuclear facility waste metal,the concentration limit of radioactive nuclide activity in intermediate ingot after melting,is determined.Finally,the surface dose rate limit(referred to as the surface dose rate acceptance limit)for receiving nuclear facility waste metal in melting plant is derived.The waste metal with a surface dose rate that meets the limit is reused to obtain a final product that meets the regulation requirements of irradiation dose rate.
