摘要
花岗岩是广东广泛分布的岩性，大部分花岗岩地区内以放射性元素背景值明显偏高为特征。由于各种矿产资源的勘探和开采，以及人为因素对表层的破坏，天然放射性辐射环境质量存在变差的趋向，而且以不同的扩散形式产生着令人忧虑的次生污染，以及对群体带来的影响和危害。本文对此通过已取得的部分资料做了比较全面的分析，并提出了急待控制和改善广东花岗岩地区天然放射性辐射环境的对策。
Granite is the commonly distributed lithology in Guangdong Province. Most of graniteareas are characterized by apparently high background of radioactive elements. Because of theexploration and exploitation of various kinds of mineral resources,and the destruction of thesurface layer by mankind,there is a trend making the enviromental quality of natural radioactive radiation worse,and causing secondary pollution to influence and harm to human beingthrough different kinds of diffusion form. According to the situation,the authors make a relatively complete analysis on the obtained data and put forward the countermeasure to improvethe natural radioactive radiation environment.
