The EPA recommends that comparison/simultaneous measurements are collected how often?

The EPA recommends that comparison or simultaneous measurements should be taken every 10th measurement. This practice is crucial in ensuring the reliability and accuracy of radon measurement results. By collecting simultaneous measurements at this specified frequency, technicians can verify that their radon measurement devices are functioning correctly and providing consistent results.

This practice serves several purposes: it helps identify any potential discrepancies between different radon measurement systems, ensures that variations in measurements are recognized and addressed, and confirms that the methodology used is effective in a variety of conditions. It enhances the overall quality of radon testing and assists in ensuring compliance with recommended radon levels, thereby safeguarding public health.

Consistent comparison measurements allow professionals to maintain high standards of measurement integrity and provide trustworthy information regarding radon exposure in residential or commercial spaces.
