Recently lower mortality for cancers of all sites was reported among inhabitants in the Misasa spa area, where there is a high radon background.
To clarify the effects of radon exposure on cancer mortality, the effects of a hot spring itself on cancer mortality was investigated in the Beppu spa area, which has only a low radon background, and adjacent control areas.
For females, the mortalities for cancers of all sites, liver and lung were higher in Beppu than those for all Japan on the basis of the standardized mortality ratio (SMR), while the SMR for all cancers was lower in adjacent areas.
For the male inhabitants in both areas the cancer mortalities of all sites were not significantly different from those of all Japan.
