天津市氡辐射状况与肺癌发病率的关系

The Relationship of Radon Exposure and Incidence of Lung Cancer in Tianjin Area

目的 探讨地质断裂带及非断裂带之间氡辐射状况与肺癌发病率的关系。方法 采取单纯随机抽样的方法 ,对 6 9户断裂带及 135户非断裂带居民居室内氡及子体的浓度进行了测定 ,并应用单因素方差分析和 t-检验分析其与天津市肺癌发病率的关系。结果 断裂带肺癌发病率明显高于非断裂带 ,t=10 .85 ,P<0 .0 1;且断裂带与非断裂带居民居室内氡及子体的浓度比较 ,差异有显著性 ,t=2 7.0 9,P<0 .0 1。结论 肺癌发病率与居民居室内氡及子体的浓度有相关性。

ObjectiveTo study the relationship of Radon exposure and incidence of lung cancer between the fault zone and non-fault zone.MethodsDouble samples of 69 families in fault zone and 135 families in non-fault zone were recruited randomly in this study.The levels of radon in their rooms were measured.One-Way ANOVA and T-test were used in this study.ResultsThe incidence rate of lung cancer was higher in fault zone than in non-fault zone,t=10.85,P<0.01;The levels of radon in their rooms were difference between fault zone and non-fault zone,t=27.09,P<0.01.ConclusionThere was a relationship between radon exposure and incidence of lung cancer.
