Using aggregate data for the counties of England and Wales, a negative association is found between mean radon concentrations in dwellings and lung cancer standardised mortality ratios, when regional smoking variations, diet variations, social class variations and population density are controlled. Cornwall and Devon have the highest mean domestic radon gas concentrations, yet the number of lung cancer deaths there was within the range to be expected from relationships not involving radon observed in the rest of the country. While high values of radon exposure appear to concentrate in particular localities, the variations in lung cancer mortality between districts in Cornwall and Devon are small. These findings do not refute the linear exposure-risk hypothesis, but the evidence suggests that relatively few, if any, radon related deaths were associated with the dwellings where radon gas concentrations exceeded the recommended action level.
