The International Radon and Vapor Intrusion Symposium brings trade professionals, scientists, educators, policymakers, advocates, consumers and more together to learn, collaborate and connect. The Symposium attracts hundreds of attendees annually from around the world. 


The annual symposium is the essence of community. Community is about being connected.  The most lasting connections our professionals have made, so often are made at the symposiums. Join us this year and grow your community!


For over 35 years, AARST’s mission statement, “dedicated to the highest standard of excellence and the ethical performance of radon measurement, mitigation, and transfer of information for the benefit of members, consumers, and the public at large” has been at the heart of every symposium. Annually, dozens of practitioners, educators, and researchers assemble to share their knowledge. This information transfer doubles with the added benefit of Continuing Education credits for radon certifications and licenses.
