摘要
目的了解武汉市居室内γ辐射水平和氡浓度,为控制室内放射性污染提出预防措施。方法依据我国现行有关建材的放射性和氡的标准。结果居室内γ辐射水平范围为11.32±4.21～15.12±3.92,氡浓度范围为19.24±5.83～34.47±5.74。结论居室内墙体材料以废渣砖结构的γ辐射水平和氡浓度最高,γ辐射水平和氡浓度在不同季节、不同楼层有明显差别。
Objective To find out the indoor gamma radioactivity level and gamma concentration in Wuhan and take preventive measures to control indoor pollution.~Methods Based on the current radioactiveity and radon criterion for building materials.~Results Indoor gamma radioactivity levels ranged from11.32±4.21 to 15.12±3.92; radon concentrations radged from19.24±5.83 to 34.47±5.74.Conclusion The Indoor gamma radioactivity level and radon concentration are the highest in houses built with bricks of waste materials; there is no significant difference in the level and concentration in different seasons and floors.
