Radon Action Plan publishes general information about radon gas, radon testing, and radon mitigation. It is for informational purposes only. It is not medical advice and it is not a substitute for diagnosis, screening, or treatment by a qualified healthcare professional. Radon exposure is a recognised cause of lung cancer, and if you have questions about your own health or your own exposure history, raise them with your doctor.
We are not a licensed radon measurement or radon mitigation contractor, and nothing here is a professional measurement or a mitigation design. Test results, action levels, and any decision to install or modify a mitigation system should be confirmed with a certified radon professional and with your state or provincial radon program, whose requirements differ by location.
