What is the Surgeon General's stance on Radon testing in homes?

The Surgeon General's stance emphasizes the importance of radon testing for all homes, highlighting the significant health risks associated with elevated radon levels. Testing is particularly critical because radon is a colorless, odorless gas that can accumulate in homes, increasing the risk of lung cancer upon prolonged exposure.

The recommendation for remediation if radon levels are 4 pCi/L or higher is grounded in scientific research indicating that this threshold poses a heightened risk. By advocating that every home be tested, the Surgeon General aims to ensure that homeowners are aware of their radon levels and can take appropriate action to protect their health. This public health directive underscores the need for proactive measures rather than reactive ones, as radon testing in older homes, rentals, and even new constructions is essential to safeguard occupants from potential health hazards associated with radon exposure.

In this context, options that suggest limited testing (only for new homes or only in high-risk areas) fail to recognize the universal applicability of radon hazards, while the notion of annual testing, regardless of levels, does not align with the targeted remediation strategy that focuses on homes with confirmed elevated radon levels.
