贵州省含煤渣建材的放射性污染调查

The Radioactivity Level of Building Materials Mixed With Coal Cinder and The Countermeasures to its Pollution

调查研究了贵州省主要煤田及贵阳地区部分小煤矿中天然放射性核素含量水平 ,述叙了利用煤渣作建筑材料所产生的巨大社会效益和经济效益。阐明了根据煤灰 (渣 )的天然放射性核素含量水平进行分类管理的重要性 ,分析煤灰(渣 )作建筑材料存在的一些问题 。

The contents of natural radioactive nuclides in major coal fields in Guizhou and part of the coal mines near Guiyang have been investigated. The social and economic benefits from the use of coal cinder for the production of building materials are stated. Also discussed in this paper are such aspects as the importance of classified management according to the content of natural radioactive nuclides in coal fly or coal cinder, problems arising from the application of coal fly(coal cinder) to building materials and the countermeasures to the radioactive pollution.
