摘要
历年伴生放射性矿调查中发现,不少废渣中的放射性核素活度比环境样品要高出几个数量级,部分废渣铀钍系单个核素放射性核素浓度远大于1 Bq/g的管理值。本文从废渣分类管理角度出发,研究按放射性核素浓度进行对废渣划分,再探讨如何在废渣运输过程中采用有效的环境保护措施手段避免其不对周边环境产生放射性污染;研究中对放射性废渣的包装、运输线路选择、运输期间道路的管理等几个方面进行了详细的探讨,以便于日常工作中对该类废渣运输具有一定的参考意义。
It is found in the investigation of associated radioactive ore over the years, the activity of radionuclides in many wastes is several orders of magnitude higher than that in environmental samples, the single radionuclide concentration of uranium and thorium in some waste residue is much higher than the management value of 1 Bq/g. From the perspective of waste residue classification management, this paper studies the classification of waste residue according to the concentration of radionuclide, and then discusses how to use effective environmental protection measures in the process of waste residue transportation to avoid radioactive pollution to the surrounding environment. In the research, the packaging of radioactive waste, the selection of transportation route, the management of road during transportation and other aspects are discussed in detail, so as to provide reference for the transportation of this kind of waste in daily work.
