What percentage of tests are duplicates in radon measurements?

In radon measurement protocols, the standard practice is to conduct duplicate tests to ensure the reliability and accuracy of the radon levels being reported. A common industry guideline suggests that approximately 10% of tests should be duplicates. This practice helps account for variability in measurements due to factors such as equipment precision, environmental influences, or sampling errors.

By having a duplicate test, technicians can assess the consistency of the radon measurements, identify potential anomalies, and provide clients with more reliable results. Adhering to this 10% standard not only supports the quality assurance processes but also enhances confidence in the findings presented to homeowners and clients about radon exposure risks. The consistent use of this percentage in radon testing further solidifies its acceptance and application in the field.
