摘　　要：本文汇总了我国部分地区室内外氡浓度调查结果,特别指出了铀矿区附近、煤渣砖和石煤渣砖建筑物、窑洞、地下室及高本底地区室内的氡水平。确定了剂量评价中所采用的氡子体暴露量-有效剂量转换因子、平衡因子及室内停留因子,给出有效剂量估计值。最后。The survey results of indoor and outdoor radon concentrations in some areas of China are summarised in this paper,particularly in dwellings near uranium mines,buildings made of cinder bricks and stone like coal cinder bricks,cave dwellings,underground buildings and dwellings in high background radiation areas. In dose assessment the values of exposure effective dose conversion factor,equilibrium factor and occupancy factor indoors are defined,and annual effective dose estimations are given. The problem of protection against radon in buildings is discussed briefly.
