What about radon and radioactivity in granite countertops?
Recently I came to know about this.
Edit: I should have added an explanation. It is only an issue when the ventilation is very low. Accumulation of Radon gas is the only thing to be worried about.
Aah I should have clarified more. My bad.
This is only an issue when the ventilation is very low, means when accumulation of Radon gas happens in some form. In spaces with ventilation it should not be a problem.
But Radon is “one of the leading causes of lung cancer, in non-smokers” . So not critical, but caution must be there is what I understood.
