Plots of lung cancer rates corrected for smoking prevalence vs. average home radon levels are presented for U.S. counties with a wide variety of socioeconomic characteristics. The data are generally well described by the same negative slope linear, plus positive slope quadratic, "standard" curve. Plots are presented for geographic regions and these are also reasonably well fit by the standard curve. The findings are not consistent with predictions based on a linear no-threshold model.
针对具有广泛社会经济特征的美国各县,给出了经吸烟率校正后的肺癌发病率与家庭平均氡水平的关系图。这些数据通常能很好地用相同的负斜率线性加正斜率二次“标准”曲线来描述。还给出了各地理区域的关系图,这些图也能较好地拟合标准曲线。研究结果与基于线性无阈模型的预测不一致。
