摘　　要：用工业废渣生产的混凝土实心砖,生产过程中会出现富集和迁移现象,具有较高的放射性水平。通过试验发现,混凝土实心砖放射性核素限量值会随着掺入工业废渣的比例不同而发生改变,总体与原材料放射性核素限量值呈正比例关系,但不构成曲线关系。对高放射性工业废渣应慎用,确需使用的比例应不超过50%。The concrete solid brick produced from industrial waste will appear the phenomenon of enrichment and migration in the production process,which often has a high radioactive level.Through the test,it is found that the radionuclide limit value of concrete solid brick will change with the different proportion of industrial waste slag,and it has a positive proportional relationship with the radionuclide limit value of raw materials,but it does not form a curve relationship.Therefore,the high-level radioactive industrial waste should be used with caution,and the proportion that must be used should not exceed 50%.
