How far apart must detectors be to be considered in separate locations and reported individually?

Detectors must be placed at least 8 inches apart to be considered in separate sampling locations and reported individually. This spacing guideline is crucial because it helps ensure that the radon measurements obtained from each detector reflect distinct environmental conditions and are not influenced by the same radon source or airflow patterns. Proper spacing minimizes the risk of correlated results, which could lead to inaccuracies in assessing radon levels in the areas being tested. By adhering to this 8-inch separation standard, practitioners can more reliably characterize radon concentrations throughout different areas of a property, thereby providing more accurate risk assessments and recommendations for mitigation if necessary.
