摘　　要：采用石材产品放射防护分类控制标准，应用地面γ能谱测量、γ总量测量、采集样品后在室内进行定量核素分析等方法对全国21个石材矿床进行了放射性评价，并介绍了评价指数、进行此种评价的意义及工作方法．详述了在广西岑溪县红色花岗石矿床上进行的工作。The radiological assessment of building material deposits is introduced, including its principle, working procedure and importance. Twenty one deposits of natural stone were assessed with radiomettic methods such as gamma energy spectrum and dose measurements and ganuna logging in the field, nuclide analysis of specimens in the laboratory, etc. As an application example, the assessment of a red-granite deposit located at Cenxi County of Guangxi is described in detail.
