True or False: Devices must be assessed through NRPP's Device Evaluation Program before becoming approved.

Devices designed for measuring radon levels must indeed undergo assessment through NRPP's Device Evaluation Program prior to receiving approval. This thorough evaluation process ensures that the devices meet specific performance standards and reliability criteria necessary for accurately measuring radon concentrations. Such rigorous testing is critical in establishing the credibility of measurement results, which can influence public health decisions and remediation actions.

By ensuring that all devices, regardless of whether they are passive or active, undergo this evaluation, NRPP maintains a high standard for radon measurement tools, instilling confidence in their usage among professionals and homeowners alike. The process also helps to reduce the risk of inaccurate measurements that could lead to false assumptions about radon exposure and associated health risks. Therefore, the statement that devices must be assessed before approval is true.
