论燃煤过程中的放射性污染

On The Radioactive Contamination Caused From Coal Burning

国内煤层中普遍存在的天然放射性核素,通过燃煤产生的烟气、煤灰渣等介质进入空气、土壤和水环境中。公众健康危害评价结果证明燃煤排放的放射性污染物通过吸入途径对人体的总危害危险大于二氧化硫、氮氧化物等一般污染物。鉴于我国近几年火电厂等煤炭消耗量大,并且不断增长的现状,指出对燃煤造成的放射性环境污染应予足够的重视。

Radioelement existing in domestic coal beds is discharged into atmosphere, solid and water environment via medium of smoke coal ash and slag etc. The results of impact assessment of radioelement to public health shows that the mentioned impact is normally severer than impact from sulfur dioxide, nitrogen oxide and soon. In term of it being the facts that the quantity of domestic coal consumption not only belonging to a vast quantity but also increasing day by day, it was claimed that the impact of radioelement to public health should be emphasized adequately.
