工业废渣及建筑材料的天然放射性水平

Natural Radioactive Level in Industrial Waste Slags and Building Materials

报道了粉煤灰、煤渣、铝矾土和花岗岩等工业废渣和建筑材料中的天然放射性水平 ,包括原料和成品堆场表面 γ照射量率和样品中的天然放射性核素比活度 ;对部分建材测量了建筑物室内的 γ辐射剂量率。结果表明 ,除个别地区的样品外 。

This paper reports the measurement methods and results of natural radioactive level in industrial waste slags and building materials,such as coal ash,cinder,bauxite and granite.Surface gamma exposure rates of materials and products,as well as specific activity of natural radionuclide in samples are detected.For part of building materials,gamma radiation dose rates in buildings are also measured.
