Easy systems of reduction have actually been revealed to be with the ability of lowering interior radon degrees by more than 50%. When radon air flow fans are added radon degrees can even be lowered additionally. The risk of lung cancer cells boosts by 16% per 100 Bq/m3 rise in very long time typical radon concentration. The dose-response relation is straight-- for instance, the danger of lung cancer cells raises proportionally with enhancing radon exposure. The reduced the radon concentration in a home, the lower the danger of lung cancer cells as there is no known threshold below which radon direct exposure carries no threat.
