摘　　要：在分析泉州地区常见花岗石石材的类型及其岩石的矿物成分等特征的基础上,指出不同矿物成分及其所呈现的不同颜色系列的花岗石石材,放射性强度存在一定差异,认为基性岩类和中性岩类,即暗色系列和灰色系列的花岗石石材,放射性强度低,使用较为安全;而酸性岩类,即浅色系列的花岗石石材应区别对待,使用前应进行必要的放射性检测.Based on rock type and its mineral characteristics of common granites as building material in Quanzhou,the different rocks and mineral conposition on radioactive intensity of granites as building materials are discussed. Granites as building materials of the dark-color systems and the gray-color systems are radioactive safe,because they have low radioactive intensity. It is necessary that the radioactive intensity of the light-color granites as building materials must be determined before using.
