摘要
根据广东沿海河流阶地沉积物形成的复杂性,研究了沉积物的热释光零化作用机理,提出了确定沉积物开始时的热释光剩余值的新方法。对较老沉积物的热释光量常接近饱和状态或沉积物的TL信号与辐射剂量之间处于非线性状态时,如何求得天然热释光的等效剂量等问题进行了探讨。
The mechanism of Thermoluminescence of the sediments reduced to a residual level has been investigated on the basis of complex nature of step terrace sedim- ents forming of Guangdong coastal rivers. A new method determining thermolu- minescence surplus value of the earliest sediments has been put forward. When thermoluminescence dose of the older sediments is colse to saturation state or the state between thermoluminescence dose and radiation dose is non-linear, how to obtain the equivalent dose of natural thermolumisceuce has been studied. the res- earch work shows that the results is siguificant and satisfactory.
