What should be noted in the test report if the home is not occupied during the radon testing period?

Noting that the home is not occupied during the radon testing period is important because it provides context for the test results. When a house is empty, there may be variations in indoor air pressure and ventilation, which can affect radon concentrations. Recording the vacancy helps clarify the conditions under which the test was performed, which can be relevant when interpreting the results, especially if the radon levels are higher than the action level.

For instance, if future tests are conducted or if there is a discussion regarding the results, knowing that the home was unoccupied during testing can help stakeholders understand any potential fluctuations in radon levels due to lack of human activity, which often impacts air circulation and the overall dynamics within the home. This notation maintains accuracy and integrity in radon measurement reporting, allowing for more informed decision-making based on the test outcomes.
