If there is evidence of tampering during a test, what should be done?

When evidence of tampering during a radon measurement test is observed, advising the client that the results may not be valid and recommending a retest is the appropriate course of action. Tampering can compromise the integrity of the testing process, leading to unreliable results that could affect health decisions and remediation actions.

Retesting in such situations ensures that accurate data is collected, which is crucial for assessing radon levels and making informed decisions regarding safety and mitigation measures. This approach emphasizes transparency and maintains professional integrity, as it informs the client about potential issues that may have influenced the test results. It also demonstrates a commitment to accurate measurement practices, which is essential in the field of radon measurement.

Continuing with the test or ignoring the tampering would risk presenting misleading results, potentially putting individuals at health risk if radon levels are inaccurately assessed. Notifying authorities, while important in cases of severe violations, is not the standard response for every instance of tampering, especially if it pertains to the validity of the test results and not to immediate legal or safety issues.
