The Environmental Protection Agency (EPA) has established an action level for radon at 4 picocuries per liter (pCi/L). This threshold represents the level at which action should be taken to reduce radon exposure in homes and buildings. The EPA recommends that if radon levels are 4 pCi/L or higher, mitigation measures should be implemented to lower the radon concentration. This recommendation is based on scientific research that correlates elevated radon levels with an increased risk of lung cancer, and thus, the agency aims to protect public health by encouraging actions at this specified level.

The action level reflects a balance between risk and practicality, providing a clear benchmark for homeowners and mitigation specialists to follow. It serves as a critical guideline in radon testing and remediation practices, helping ensure safe indoor air quality.
