| 摘 要： | 释光测年中影响环境剂量率(D)的主要因素包括含水量、宇宙射线、α值(α辐射相对于γ辐射产生释光的效率)和氡逃逸等.为研究这些影响因素对D值的影响程度,采用不同的参数值对一个假定U、Th和K含量已知的样品进行了较详细的定量计算.研究结果表明,含水量变化对环境剂量率影响最大,影响程度甚至可达50％以上；其次为宇宙射线的影响...

| Abstract: | The environmental dose rate（D） in luminescence dating can be influenced by water content,cosmic ray,factor a,radon escape,etc.A series of detailed quantitative calculations were applied to the sample A1 with given U,Th and K content for D values using different parameter values of water content,cosmic rays,factor a.The calculations show that the greatest influence is up to 50% with the changes of water content,and the influence from cosmic rays is up to 15%.The influence from factor a is relatively smaller because it usually is a given constant value.The radon escape will bring an error no more than 8%. |
