我国石煤碳化砖房致居民集体有效剂量当量的估算

COLLECTIVE EFFECTIVE DOSE EQUIVALENT FOR POPULATION LIVING IN BUILDINGS OF STONE LIKE COAL CARBIDE BRICKS

本文报导了我国石煤碳化砖的历年总产量及其放射性核素^(226)Ra、^(232)Th、^(40)K的比活度。估算了室内γ吸收剂量率和平衡氡浓度及这种建筑物施于居民的附加集体有效剂量当量。

This paper describes over the years ortput and specific activity of^(226)Ra^(232)Th^(40)K for stonelike coal car- bide bricks in China. A estimations of indoor absorbed dose rate in air and meen equilibrium equivalenl radon concentration are reported. The additional annual collective effective dose equivalewt for population living in buildings of stone-like coal carbide bricks was estimated.
