What condition may indicate tampering during a radon test?

A change in the placement of a radon test can serve as a strong indication of potential tampering. Radon testing is sensitive to its environment, and the location where a test is conducted must be consistently maintained to ensure accurate results. If the test is moved from its original position, this could introduce variables that affect radon measurements, such as altered air flow or changes in the build-up of radon gas around the detector. Accurate radon levels are highly dependent on specific conditions, including placement in an area with minimal disturbances. Tampering typically results in inconsistencies that can skew data, making it crucial to monitor for any changes in the testing location.

Conditions such as normal temperature fluctuations, stable indoor air quality, and consistent radon levels are expected aspects of a typical radon test that do not inherently suggest tampering. Instead, they signify a controlled environment conducive to reliable readings.
