What level of radon gas is considered safe?
There is no apparent safe level of exposer for radon gas. The higher the levels and the longer you are exposed to radon gas the greater your risk of getting lung cancer. In a recent study combined data from across North America estimate that ones risk of developing lung cancer increases by 11% per 100 becquerels per cubic meter ( Bq/m³) increase in radon concentration, with no apparent safe level of exposure.
