摘要

报道了我国主要原煤及粉煤灰中的天然放射性核素水平．分析了煤在燃烧过程中的除尘灰和飞灰对原煤中的放射性核素浓缩倍数，并与国外进行比较．同时将上海２５０ＭＷ燃煤电厂排放的放射性水平与国外核电站排放的放射性水平进行了比较。

Abstract

An assessment of the environmental environmental radioactive level in fly ash released from coal fired power plants was carried out.The contents of natural radionuclides 238U232Th226Ra

210Po and 210Pb in coal

bottom ash and fly ash samples were determined. Radionuclides were concentrated in the stack fly ash with a concentration factor of 1.4-17.2 in China.The radioactive emission levels from coal fired power plants were compared with those from nuclear power plants.
