What is the primary focus of the Radon Rule?

The primary focus of the Radon Rule is to limit exposure to radon in air from household water usage. Radon is a naturally occurring radioactive gas that can seep into homes through groundwater, particularly when water is used in activities such as showering, washing dishes, or doing laundry. The Radon Rule aims to reduce the health risks associated with radon exposure, which can lead to respiratory problems, including lung cancer. By setting standards for radon levels in drinking water, the rule highlights the connection between water usage in homes and the potential for increased radon exposure in the air. Therefore, the emphasis is on ensuring safe drinking water while protecting public health from the risks posed by radon gas.
