False low results in radon testing are primarily associated with which scenario?

False low results in radon testing are primarily associated with improperly informed occupants. When occupants are not properly informed about how to conduct radon testing, they may inadvertently influence the results. For example, if they open windows or doors during the testing period, use exhaust fans, or fail to close the basement door, these actions can dilute indoor radon concentrations, leading to inaccurately low readings.

Another dimension is that occupants may not understand the importance of maintaining a stable environment during the testing period. This lack of proper information can lead to behaviors that skew the results, potentially causing misinterpretation of the radon levels in the home. Thus, it is crucial for occupants to be well-informed and follow testing guidelines strictly to ensure accurate readings.

Other options, such as high occupancy rates, absence of testing, and testing too frequently, do not directly lead to false low results in the same way as misinformation does. They may influence the testing scenario but are not as critical in causing a misunderstanding of radon levels.
