摘要
天然热释光量和年剂量是热释光断代工作中两个重要参数 ,它们代表着标本周边环境的放射性辐射水平。实验数据表明 ,环境辐射水平受到基底岩性的控制影响。经过长期改造 。
The natural thermoluminescence (TL) and annual dose of a sample are two important parameters in the TL dating. They represent radioactive radiation level of surroundings around the sample. Experimental data show that radiation level of surroundings depends on the control influence of lithology. After a long time reconstruction, the radiation level of the earth surface surroundings will be diminished gradually and become homogeneous.
