A recent study has revealed that nearly 25% of Americans reside in regions with radon levels deemed unsafe by the EPA. Radon, a radioactive gas originating from uranium decay in soils, has no known safe exposure level and is the second leading cause of lung cancer in the US, resulting in approximately 21,000 deaths annually. Researchers mapped areas exceeding the EPA's action level of 148 Bq/m³, identifying radon hotspots primarily in the Great Plains, Kansas, Colorado, Ohio, and Pennsylvania. Alarmingly, over 83 million Americans are in homes with high radon levels despite being in low-risk zones, underscoring the necessity for better surveys and awareness.
Over time, it can accumulate to harmful concentrations in poorly ventilated spaces, highlighting the need for awareness and mitigation strategies against radon exposure.
Researchers found that over 83 million Americans live in homes with radon concentrations over 148 Bq/m³, even in low-radon zones, emphasizing the need for comprehensive surveys.
