摘要
〔目的〕全面系统研究进口石材的放射性水平。〔方法〕对721批进口石材的放射性水平进行检测,并对γ辐射剂量率和核素分析结果的关系进行统计学分析。〔结果〕γ照射剂量率检测结果与核素分析结果有对应关系,并找出了线性回归方程。
Objective To investigate the situation of radioactivity in imported rocks roundly. Method 721 criticizes of imported rocks were tested,and the data were analyzed. Results There was correspondence between γ-equivalent dose rate and the result of nuclear analysis. The linear equation of them was observed. Conclusion It is necessary to set up the external exposure index for the radioactivity of imported rocks.
