Detectors should not be situated less than how far from other test detectors and nearby objects?

Detectors should not be situated less than 4 inches from other test detectors and nearby objects to ensure accurate measurement of radon levels. This distance helps prevent interference that could arise from the proximity of other devices or objects, which may trap or reflect radon gas and skew the readings. Ensuring a minimum separation distance aids in obtaining a consistent and reliable measurement, leading to better assessments of radon concentration in the environment. This guideline is established to maintain the integrity of the measurement process and ensure that the data collected reflects true radon levels without contamination from external factors.
