Update NCSL's Work on Radon

One of the top concerns regarding radon policy is the fact that there is no mandatory radon testing or mitigation laws. Rather, any requirement to test a house for radon or reduce radon hazards must come from the states (or in some instances, local jurisdictions). EPA does provide technical assistance to states in designing and developing a radon program, but it cannot mandate that a state take on such a program.

That being said, almost every state has established some sort of radon program. Several states require that radon tests be disclosed to buyers of a home, though none require testing be done. Tests are required for schools and in day care centers in many states. If high levels are detected, certain states require the mitigation of the radon hazard. Nineteen states require contractors who mitigate be certified, and 8 states adopted standards for radon-resistant new construction.
