The present study focuses on the effect of natural radioactivity of some common building materials to humans. The main radiological risk assessment parameters such as radium equivalent, dose rate, annual effective dose equivalent and hazard indices were determined using Gamma ray spectrometry for individual building materials and their three different combinations. On comparing the results with world average values, it is inferred that the building materials do not pose any radiation hazards. Also as all the radiological parameters for M-sand are much lesser than that of river sand, it can be a good replacement for river sand.

使用伽马射线光谱法对某些建筑材料进行辐射分析

本研究侧重于一些常见建筑材料的天然放射性对人类的影响。主要的放射学风险评估参数，如镭当量、剂量率、年有效剂量当量和危险指数，是使用伽马射线光谱法对单个建筑材料及其三种不同组合进行确定的。将结果与世界平均值进行比较，推断该建筑材料不会造成任何辐射危害。此外，由于 M 砂的所有放射性参数都比河砂低得多，因此它可以很好地替代河砂。
