Welcome to Indoor Environments 2024™ Radon and Vapor Intrusion Symposium, formerly the AARST International Radon and Vapor Intrusion Symposium.

Indoor Environments Association is a nonprofit professional technical organization that serves a unique role as an ANSI-AARST standard-setting body, demonstrating long-term stewardship and providing its accredited professionals with the tools and education to be leaders in the soil gas industry.

As IEA grows, the symposium also grows the range of attendees and vendors. Attendees are technicians in the field of radon and vapor intrusion measurement and remediation, states and tribes program leaders, and increasingly more environmental companies attend for training and to expand their forums. Indoor Environments 2024 is the definitive source for government agencies, advocates, educators, scientists, and companies sourcing field application-based needs seeking the leading indoor environments gathering annually.

Priority List and Purchasing Has Ended

Exhibitors with 20 points or more are listed on the Priority List annually. Exhibitors with the highest number of points select first during pre-determined selection dates. To qualify for placement on the Priority List annually, exhibitors must be IEA members in good standing. Once the Priority List selection period has ended all other vendors with less than 20 points may purchase and be assigned their selections on a first come first serve basis.

Points accrued during the season will total on each “vendor dashboard”. All products have points assigned to them. Booth attendee registrations do not accumulate points. Points accrue over the 3 most recent consecutive years. The 2024 points listed below are calculated from 2023 + 2022 + 2021. If vendors have not exhibited or sponsored on any given year during the accrual period, that year is represented as “0” in their point calculation. Older points drop from the accrual formula annually.

Exhibitors are assigned a week to select

At the end of each selection period, exhibitors are assigned booth space(s) and sponsorship item(s), based on their place on the PL. Availability is updated at the start of the selection period or next week. Priority Selection period is February 19 through March 22. After March 22 all remaining booths and sponsorships are available to purchase on a first-come, first-served basis.

Choosing your booth: The booth store has options during the checkout process for 1st, 2nd, and 3rd choices for booths. Choices are ranged in rows or specific large booth numbers.
