The following chart shows the risk to smokers, non-smokers and the general population based on average radon exposure. Guidelines for most environmental pollutants regulate exposure levels to at least 1 in 1,000,000 deaths. Notice that even at very low exposure levels, radon still kills many more people than one in a million. You need to get your home radon level as low as possible.
