What action should be taken if the results indicate very high levels?

When high levels of radon are detected, the most responsible and effective course of action is to consider a comprehensive remediation strategy. This approach aligns with health and safety best practices, as prolonged exposure to elevated radon levels can significantly increase the risk of lung cancer.

Implementing a comprehensive remediation strategy involves evaluating the properties and systems of the building to identify the most effective methods for reducing radon levels, such as improving ventilation, sealing entry points, and utilizing active radon mitigation systems. By taking this proactive step, one addresses the problem directly and protects the health of the occupants.

In contrast, conducting further tests without taking remedial action can lead to unnecessary delays in addressing the health risks associated with high radon levels. Simply waiting for natural variations is not a reliable solution, as radon levels do not fluctuate enough to warrant complacency. Ignoring the findings as outliers is inherently dangerous, as it disregards the serious implications of high radon concentrations and risks the well-being of individuals in the affected environment.
