为了正确的估算瓷器热释光测定年代中的古剂量,对瓷器古剂量的来源、组成和标定进行了分析.在使用前剂量技术的热释光测定年代中,瓷器古剂量的主要成分是来自瓷器内部自然辐照的β剂量,其次是环境剂量,α剂量可以忽略.测量古剂量的样品厚度在0.2～0.5mm之间.当实验室β源辐照这样厚度的样品时,β剂量在样品中的分布是非线性的,所以β剂量只能用平均值来计算.根据β剂量在样品中的积累和衰减效应,得到了β剂量在样品中的分布曲线和平均剂量的计算方法.各种厚度样品的β平均剂量可以用文中公式进行计算.
The origin, composition and calibration of ancient porcelain dosages were analyzed in order to correctly estimate the ancient dosages in porcelain during the determination of thermoluminescence.The main components of the ancient porcelain dosages came from the thermoluminescence dating of the former dosimetry Porcelain interior radiation β dose, followed by the ambient dose, α dose can be ignored.Ancient dose of the sample thickness measurement between 0.2 ~ 0.5mm.When the laboratory source β radiation such a thickness of the sample, β dose in the sample In the distribution is non-linear, so the β dose can only be calculated using the average.According to the β dose in the sample accumulation and attenuation effect, the β dose distribution curve in the sample and the average dose calculation method.All kinds of thickness The average β dose for a sample can be calculated using the formula in the text.
