摘　　要：文中介绍放射性基本原理及利用低本底多道高纯锗γ能谱仪检测陶瓷砖放射性的技术方法,对比0-14天不同平衡时间条件下陶瓷砖放射性核素的检测结果并进行分析,对合理优化陶瓷砖放射性测量的平衡时间,完善放射性检测技术水平具有一定的参考价值。结合近五年陶瓷砖专项质量监督抽查数据分析,陶瓷砖产品放射性指标均处于合格水平,有效消除陶瓷砖产品放射性安全隐患,保证市民健康安全。This paper introduces the basic principle of radioactivity and the technical method of detecting the radioactivity of ceramic tiles by using low background multi-channel high purity germaniumγ-spectrometer,to compare and analyze the test results of ceramic tile radionuclide under different balance time conditions from 0 to 14 days,improving the level of radioactive detection technology has a certain reference value.Based on the analysis of the special quality supervision data of ceramic tile in recent five years,the radioactive indexes of ceramic tile products are all at the qualified level,which can effectively eliminate the hidden danger of radioactive safety of ceramic tile products and ensure the public health and safety.
