Do marble countertops emit radon?

However, the levels are typically extremely low and not considered a significant health risk by agencies like the EPA A. ?? Key Points: • Marble is less likely than granite to emit measurable radon. • The amount released is usually well below indoor air safety thresholds. • Radon exposure risk from marble countertops is considered negligible compared to other sources like soil or poorly ventilated basements. ?
