建筑材料样品密度效应研究

介绍用低本底γ能谱仪对不同密度状态下的建筑材料样品的γ能谱进行测量分析,来确定建筑材料中天然放射性核素的含量与其密度之间的关系;并利用指数函数曲线拟合的方法,来拟合材料密度与探测效率之间的关系曲线.同时对测量的方法、原理、刻度以及测量和分析中存在的一些问题进行了讨论.

Effect Of Sample Density Of Building Materials

This paper represent measurement and analysis of gamma spectra of the samples of different density building materials by using of low background gamma spectrometer,to determine the relationship between content of natural radionuclides in building materials and its density,and use of exponential function curve fitting method to fit the relationship curve between the material density and the detection efficiency.The paper also discussed on the existing issues of measurement methods,principles,scale,measuremen...
