| 摘 要： | 本文导出一次击中和二次击中相叠加的响应函数,作为描述各种γ辐射剂量计响应的基本方程,引入特征剂量D_0和一次击中因子R,并阐明了辐射剂量响应的线性、超线性和亚线性与这两个参量的关系。模型计算与实验结果相符合。

| Abstract: | On the basis of the stochastic property of quantized events,produced by gamma rays interacting with the medium,and the concept of hit in microdosimetry,a function derived from statistical poisson distribution is generalized to describe the dose reponses for various gamma radiation dosemeters as a fundamental equa-tion.It is described that the inearity,sublinearity and supralinearity of gamma dose responses depend on the two haracteristic parameters,characteristic dose Do and one hit factor R.Our experimental results of gamma dose-responses of alanine ESR dosemeter,film dosemeter and LiF(Mg,Cu,P)and LiF(Mg,Ti)thermaol-uminescence dosemeter,show a good agreement with theoretical calculations. |
