In Karst geologic regions, what is recommended regarding radon testing?

In karst geological regions, it is particularly important to conduct repeated tests during different seasons due to the unique characteristics of these areas. Karst formations, which are created by the dissolution of soluble rocks (like limestone), can lead to varying radon concentrations based on environmental factors such as temperature, humidity, and seasonal changes.

By performing tests in different seasons, you can capture a more comprehensive picture of radon levels, as short-term or single tests may not reflect typical conditions. This approach helps ensure that results are representative and reliable, allowing for better assessment and mitigation strategies if high radon levels are detected. Continuous monitoring can provide valuable insight, but seasonal variations are crucial for accurately understanding radon risks in these distinct geological settings.
