Radon Resources: The Best External Links for Testing, Mitigation, Health, and Education
If you’re trying to learn about radon, test your home, understand your risk, or find a qualified professional, it helps to start with the most credible sources. This page is a curated directory of radon resources outside of RadonRN.com—organized by category so you can quickly find what you need.
We prioritize authoritative sources such as U.S. government agencies (EPA, CDC), major health organizations, university-backed programs, and recognized standards bodies. Links may change over time, but these organizations are stable “anchors” in the radon world.
Government & Public Health (Start Here)
U.S. Environmental Protection Agency (EPA) – Radon
The EPA is the central U.S. authority for radon guidance. You’ll find the basics, testing instructions, action level explanations, mitigation information, and radon-resistant new construction references. (Source: EPA – https://www.epa.gov/radon)
CDC – Radon (Health Overview)
The Centers for Disease Control and Prevention provides a health-focused overview of radon, risk context, and why testing matters. This is a great place to send skeptical readers who want a medical/public-health perspective. (Source: CDC – https://www.cdc.gov/radon/about/index.html)
National Cancer Institute (NCI) – Radon and Cancer
NCI explains radon and lung cancer risk and provides a straightforward health framing for the general public. (Source: NCI – https://www.cancer.gov/about-cancer/causes-prevention/risk/radiation/radon-fact-sheet)
National Institute of Environmental Health Sciences (NIEHS) – Radon
NIEHS (part of NIH) provides radon background, exposure pathways, and health effects in a research-oriented but still readable format. (Source: NIEHS – https://www.niehs.nih.gov/health/topics/agents/radon)
Health Organizations & Awareness
American Lung Association (ALA) – Radon
ALA content is helpful for explaining radon risk and the synergy between radon and smoking. They also promote Radon Action Month and public awareness initiatives. (Source: American Lung Association – https://www.lung.org/clean-air/indoor-air/indoor-air-pollutants/radon)
American Cancer Society – Radon
A clear explanation of radon health risk, who is most at risk, and why mitigation reduces long-term harm. (Source: American Cancer Society – https://www.cancer.org/cancer/risk-prevention/radiation-exposure/radon.html)
World Health Organization (WHO) – Radon and Health
WHO provides an international viewpoint, reference levels, and a global framing for radon risk and prevention programs. Useful if you want “bigger than the U.S.” context. (Source: WHO – https://www.who.int/news-room/fact-sheets/detail/radon-and-health)
Education, Training, and Radon Programs
National Radon Program Services (Kansas State University)
One of the most useful, practical education hubs for radon. They provide training, resources, and support for radon measurement and mitigation programs. (Source: KSU / National Radon Program Services – https://sosradon.org/education)
Radon.org – Educational Resource
A public-facing educational site that helps explain radon, testing, and mitigation basics in a simplified way. (Source: Radon.org – https://radon.org)
Finding Professionals & Credentialing
EPA – Find a Radon Professional (State Contacts)
EPA maintains guidance and links that help homeowners find state radon programs and qualified professionals. Start here if you’re looking for official state contacts and program pages. (Source: EPA – https://www.epa.gov/radon/epa-map-radon-zones-and-supplemental-information)
National Radon Proficiency Program (NRPP)
NRPP lists certified radon measurement and mitigation professionals and supports credentialing standards. This is one of the most recognized credentialing bodies in the U.S. (Source: NRPP – https://nrpp.info/)
National Radon Safety Board (NRSB)
Another major U.S. credentialing organization for radon professionals, including testing and mitigation certifications. (Source: NRSB – https://nrsb.org/)
Standards & Technical Guidance (For Deeper Reading)
ASTM International (Radon Standards)
ASTM publishes consensus standards for radon measurement and mitigation practices. These are more technical and often used in professional/compliance contexts. (Source: ASTM – https://www.astm.org/)
ANSI / AARST Radon Standards
AARST (American Association of Radon Scientists and Technologists) has helped develop widely used radon standards (often referenced in professional practice and some state programs). This is a go-to destination for technical best practices. (Source: AARST – https://aarst.org/)
National Academies – BEIR VI (Radon Risk Models)
If you want the “deep science” behind radon risk estimation and epidemiology models, BEIR VI is one of the most-cited syntheses (technical, but foundational). (Source: National Academies – https://www.nationalacademies.org/publications/5499)
Radon Publications (Highly Useful PDFs)
EPA – A Citizen’s Guide to Radon (PDF)
One of the most referenced consumer-level radon documents. Great for explaining testing, interpreting results, and next steps. (Source: EPA – https://www.epa.gov/sites/default/files/2016-12/documents/2016_a_citizens_guide_to_radon.pdf)
EPA – Consumer’s Guide to Radon Reduction (PDF)
Clear mitigation guidance, what systems do, what to expect, and why post-mitigation testing matters. (Source: EPA – https://www.epa.gov/sites/default/files/2016-12/documents/2016_consumers_guide_to_radon_reduction.pdf)
EPA – Building Radon Out (Radon-Resistant New Construction) (PDF)
The classic EPA technical guide for radon-resistant new construction. Excellent if you’re building a new home or working with a builder. (Source: EPA – https://www.epa.gov/sites/default/files/2014-08/documents/buildradonout.pdf)
Quick “Where Do I Start?” Recommendations
- New to radon? Start with EPA’s radon hub and the CDC overview. (Source: EPA – https://www.epa.gov/radon; Source: CDC – https://www.cdc.gov/radon/about/index.html)
- Ready to test? Read EPA’s Citizen’s Guide to Radon for testing and interpretation. (Source: EPA – https://www.epa.gov/sites/default/files/2016-12/documents/2016_a_citizens_guide_to_radon.pdf)
- Test came back high? Read the EPA Consumer’s Guide to Radon Reduction and find a credentialed pro via NRPP or NRSB.
