| 中文摘要 | 选择不同容量、参数、除尘技术,以及不同时期发展的代表性电厂机组为对象,初步评价了当前我国部分燃煤电厂的气载放射性排放量及其辐射影响。估算结果表明,燃煤电厂对80 km范围内公众产生的归一化集体剂量平均为6.68人.Sv/GWa;不同煤耗和除尘效率的电厂机组的气载放射性排放量有显著差别,使用的煤和烟囱高度也是影响剂量的因素;主要照射途径是食入内照射和吸入内照射;气载放射性排放量越大的电厂,经吸入途径产生的剂量所占的比例越高。与天然本底水平相比,燃煤电厂的辐射影响还是很小的。; The airborne radionuclide emissions and radiation doses to the public from typical coal-fired power plants were evaluated preliminarily,which had different capacity,parameters,dust removal installations,and stage of development.The average normalized collective doses to the public from coal power plant is 6.68 man稴v/GWa.There are obvious differences between coal power plants of different coal consumption and dust removal efficiency,while the radionuclide content in coal and the stack height are influence factors.Major exposure pathways are ingestion,inhalation,and the more emissions of airborne radionuclide,the more proportion of inhalation.Compared with natural background level,radiological impacts of coal-fired power plants are very small. |
