摘要
从去污机制、方式选择、特点几方面介绍铀矿冶放射性污染金属去污的一种主要方法——熔炼法。以中核铀矿冶放射性污染金属熔炼处理中心10多年处理放射性污染金属的实践，论述了熔炼法处理放射性污染金属达到的效果：表面污染水平为4～48Bq／cm。的污染金属，经处理后降至0．004～0．016Bq／cm^2，其金属中放射性比活度〈1Bq／g，低于IAEARS—G1．7《排除豁免和解控概念的应用》提出的解控水平值，完全可供矿山及系统内部生产循环利用。
Melting method is a primary method used for decontamination of radioactive polluted metal from uranium mining and metallurgy. The decontamination mechanism of the method, the way selection and its features are introduced. Taking the ten year＇s work of CNNC Uranium Mining and Metallurgy Radioactive Polluted Metal Melting Processing Center as example, the effects of processing radioactive polluted metals by smelting method are discussed. The surface pollution levels of radioactive polluted metal from uranium mining and metallurgy decreased from 4-48 Bq/cm^2 before decontamina- tion to 0. 004-0. 016 Bq/cm^2 after decontamination, and the specific activity of its metal is less than 1 Bq/g, which is below the solution control level proposed by IAEARS--G1. 7 ＂the application of the concepts of exclusion, immunity and solution control＂. The metals after decontamination can be recycled by producing tooth plate and bucket teeth of excavator used in mines.
