Come celebrate with AARST!

The International Radon Symposium is the highlight of our year! We attend many excellent conferences in Europe. The scale of the AARST Symposium, thanks to the breadth of knowledge and experience shared by attendees, makes it invaluable for us.

Great technical and real world presentations. I learned a tremendous amount of new information and skillsets. Networking with other attendees and radon businesses was great and valuable in growing my business. This was a worthwhile investment.

The symposium is a great opportunity to learn, share, and increase action in radon reduction.
