What should be done if occupants will be moving during the RP measurement period?

When occupants are moving during the radon measurement period, it is crucial to consider the integrity and accuracy of the data being collected. If the occupants are not present in the space being tested, it may lead to misleading results. Radon levels can fluctuate based on varying factors such as airflow and building occupancy, which can be influenced by the presence or absence of occupants.

Conducting a measurement under these conditions could compromise the validity of the results, as they might not accurately reflect the typical radon levels experienced by those residing in the space. Thus, choosing not to conduct the measurement in this situation is appropriate. It ensures that future measurements will be more reliable and that proper remedial actions can be taken based on accurate data when the occupants are present or the space is stable.
