How do people handle radon exposure? Radon exposure occurs in homes and buildings, such as offices and schools. For kids and adults, most Radon gas can enter buildings through cracks in floors and foundations, construction joints, areas around wires, pumps or pipes and other openings. Radon can move from water into the air in small amounts, where it can be inhaled – but fortunately, this is not a major contributor to radon exposure. A bigger risk can occur from exposure to certain types of building materials, especially those made from natural substances, such as concrete and wallboard. In most cases many of these materials emit low levels of radon, but it may not always be the case.
Granite countertops, which are commonly found in many homes. Most health experts agree that in the majority of cases, countertops emit very low levels of radon. However, higher levels have been found in certain cases, but the EPA claims it’s doubtful these levels are higher than those emitted from nearby rocks and soil.
