环境γ辐射本底的照射量率水平及其与建筑材料的关系

The Radiative Dose Rate of Environmental γ-Ray Background Radiation and Relationship Between it and Building Materials

报导了对河北师范大学校园环境的γ辐射本底照射量率的普查结果，报导了校内部分建筑物所用的建材中放射性元素成分和含量的分析数据，阐明了γ辐射本底和建材间的关系以及严格执行国家建材放射性卫生防护标准的必要性．

This paper reported the survey results on radiative dose rate of envionmental γ- ray background radiation. and the composition and content of radiant elements in several building materials. This paper also explained the relationship between environmental γ-ray background radiation and building materials,and stressed the necessity of strict excuting national standard of radiant health protection on building materials.
