Lung cancer occurs in subjects with no history of active smoking in 15–25% of all cases,
mainly females. Lung cancer in never-smokers is a recent field of investigation, with …

Epidemiological studies of lung cancer among nonsmoking men are few. This case–control
study was conducted among lifetime nonsmoking men between 1990 and 1996 in Germany …

Eleven cohorts of miners occupationally exposed to relatively high concentrations of radon
showed a statistically significantly high risk of lung cancer, while three cohorts from the …

The aim of the study was to assess the effect of residential radon exposure on the risk of
lung cancer in never-smokers and to ascertain if environmental tobacco smoke modifies the …

In this study, we attempted to reduce existing uncertainty about the relative risk of lung
cancer from residential radon exposure among never-smokers. Comprehensive …

Exposure to indoor radon and radon daughters is currently attracting great interest as a
possible cause of lung cancer. This concern is supported by several studies, most of them …

Background: Inhaled radon has been shown to cause lung cancer among underground
miners exposed to very high radon concentrations, but the results regarding the effects of …

Radon is a naturally occurring radioactive gas in our environment. This element can reach
high concentrations in uranium and other mines, thereby causing lung cancer in various …

Background Radon is a well-established lung carcinogen that has been extensively studied.
Very high concentrations can occur in some underground mines. Concentrations also tend …

Studies of underground miners occupationally exposed to radon have consistently
demonstrated an increased risk of lung cancer in both smokers and non-smokers. Radon …
