Which requirements are generally stricter regarding radon measurements?

State requirements for radon measurements are generally more stringent than federal requirements or those from other entities such as the NRPP or local ordinances. States often tailor their regulations to reflect local geological conditions and public health concerns related to radon exposure. This means they may impose more rigorous testing protocols, establish specific guidelines for measurement equipment, and require more frequent testing in areas identified as high-risk for radon.

Federal guidelines provide a baseline for radon measurement practices, but they often allow states the flexibility to implement stricter standards. Similarly, NRPP, while it offers certification and training to professionals in radon measurement, does not set laws or mandatory practices that can supersede state-level regulations. Local ordinances, while they can impose specific requirements, typically align with state laws and might not extend beyond what the state mandates. Hence, state requirements are essential in ensuring that radon measurements are conducted in a manner that best protects public health within that jurisdiction.
