| 摘 要： | 本文报道了石煤开发利用中产生的对环境的放射性影响问题。石煤中U、~(226)Ra含量高,在其生产和利用过程中,如无任何控制措施,可以导致环境放射性污染。调查结果表明:浙江省石煤开发利用区土壤中~(238)U 和~(226)Ra 含量分别比对照区高2.4和2.1倍;陆地γ辐射水平比对照区高44%;石煤渣砖建房室内γ辐射剂量率比对照区高80%;石煤渣砖建房室内氡及其子体浓度最高分别可比一般砖建房高35和42倍,室内氡子体所致居民年附加有效剂量当量为41.2mSv;并导致钱塘江冰系某些局部江段中~(238)U 和~(226)Ra 浓度增加了一个数量级。

| Abstract: | This paper reported environmental problems from mining and utilization of bone coal.It can result in environmental radioactivitycontamination if there are no protective measures.The paper shows thatthe radioactive level of ~(238)U and ~(226)Ra in the contaminated area is2.4 and 2.1 times higher then the controlled area respectively,In comp-arision to the constructed house with normal brick the exposure in thebuilding constructed by using stohe-like coal cinder are meanly 80%higher,and the contents of radon and its daughters in the air indoors are 35 42,times higher.The effective dose equivalent from the radon daughtersis about 41.2 mSv.The contents of U and ~(226)Ra in the water are,increased by one order of magnitude in some reaches of Qiantanriver. |
