What is the recommended procedure for addressing potential bias during radon testing?

The recommended procedure for addressing potential bias during radon testing is to implement systematic checks. This approach involves establishing methods and protocols to ensure that the testing process is consistent, accurate, and free from external influences that could skew results. Systematic checks include calibrating equipment, verifying that testing protocols are followed, and reviewing test data for anomalies.

Implementing systematic checks helps to identify any potential biases before the radon levels are reported. This can involve routine quality control measures, such as using control samples, or checkpoints during the testing period to ensure that conditions remain stable. By deliberately incorporating systematic methodologies, radon professionals can maintain the integrity of the testing process, leading to more reliable and accurate measurements.

While other options may play a role in ensuring the accuracy of radon testing, they do not directly address bias in the way that systematic checks do. For instance, marking tests as incomplete does not help rectify or acknowledge any bias issues that may arise. Automated monitors can improve efficiency but rely on the accuracy of their programming and initial calibrations. Conducting periodic recalibrations is important for maintaining equipment accuracy but doesn't proactively address potential biases during the actual testing phase. Hence, implementing systematic checks is the most effective strategy for minimizing bias in radon testing.
