摘要
介绍了建筑材料放射性污染检测、控制的重要性及其危害。经研究表明 :几乎所有的建筑材料都存在不同程度的放射性污染 ,超限量的放射性会对人体造成危害。同时 ,还介绍了建筑材料放射性定量控制的两个指标及其限量标准 ,着重阐述了建筑材料放射性的测量原理和典型测量方法 ,并对几年来的一些测量结果进行了分析 ,提出了要有选择性地使用建筑材料的观点。
This text introduced the importance of the building material radioactive contamination examination, control, and nations, domestic to this contaminative control general situation;Introduced formation and its banes of the building material radioactive contamination, through study the enunciation:Almost all of the building material all exsits the radioactive contamination of the different degree, the radio of the super capacity will result in the bane to the human body;At the same time, this text still introduced two index signs and its capacity standards of the building material radio fixed amount control;Emphasize the diagraph principle that expatiated the building material emanation to measure the method with the typical model;And proceeded the analysis to the some diagraph result of several in the last yersput forward to to have to use the standpoint that construct the material optionally.
