||Bronchial dysplasia induced by radiation in miners exposed to 222Rn progeny

||This study investigated whether sputum cytology can be used to monitor epithelial cell changes in groups at high risk of lung cancer from exposure to radiation. To this end, 434 underground miners were examined of whom 334 were exposed to 222Rn progeny and 100 were not. The frequency of dysplasia in the exposed group was significantly higher than in the unexposed group and an exposure-response relation was found which was different for smokers and non-smokers. Possibly the frequencies of dysplasia could be used to assess past exposures of groups of miners. This approach could be applied to cases where data on radiation monitoring are not available or are very scarce.
