摘要
报道在正常生产情况下,用环境监测仪测定锆英石及锆英釉料瓷砖的放射性水平。锆英石的总比放射性大于7.0×10~4Bq·kg^(-1),属放射性物质;锆英釉料瓷砖的γ、β放射性污染致公众的附加年剂量当量为0.34mSv,相当于公众剂量限值的1/3。
Levels of radioac tivity in Zircom and glazed tile The results show thae averoge specific activities of zircom Are exced 7. 4×104Bq·kg-1 it is radioactive suhceance the annual eguivalent dose of γ、β-irradiation to residents caused Bg the glazed tile from the zircom is 0. 34 m Sv·a-1,eguivalent the dose to limit for one-third toresidents. .
