If a short-term test result is more than 2x the action level, what should be done next?

When a short-term radon test result is more than twice the action level, the recommended procedure is to conduct a second short-term test without delay. This is important for a few reasons.

First, test results can be influenced by temporary factors or conditions that may not represent the typical radon levels in the home. By conducting a second test, you can confirm whether the elevated radon level is consistent and reliable. This helps ensure that subsequent decisions, such as remediation, are based on accurate data rather than potentially erroneous initial results.

Additionally, if the second test also indicates high radon levels, it strengthens the case for remediation and provides homeowners with more conclusive evidence of the presence of radon in their environment. This method also aligns with best practices in radon measurement, as it ensures that actions taken are appropriate and based on comprehensive data.
