What is the action level for radon in WL?

The action level for radon in working level (WL) is set at 0.02 WL. This value is significant because it represents a threshold beyond which remediation or mitigation efforts typically become necessary to reduce radon exposure in buildings.

Understanding this level is crucial for radon measurement technicians as it informs their recommendations for homeowners and the actions needed to protect individuals from the risks associated with elevated radon levels. When readings are at or above the action level, it indicates a heightened risk of lung cancer due to radon exposure, and prompt action is crucial to mitigate this risk.

The setting of the action level at 0.02 WL is based on extensive research and is intended to balance the need for protecting public health while considering practical concerns associated with remediation efforts. This level provides a clear guideline for both professionals and the public regarding safe indoor air quality standards related to radon exposure.
