This news is based on the following article: Vienneau D, de Hoogh K, Hauri D, et al. Effects of radon and UV exposure on skin cancer mortality in Switzerland. Environ Health Perspect 2017; 125: 067009. doi: 10.1289/EHP825
This nationwide study suggests that in Switzerland, residential exposure to radon is as important a risk factor for melanoma as UV exposure. Further study based on incidence data rather than mortality is needed for a better understanding of the role of radon exposure in skin cancer, including rarely fatal forms.
