Indoor Environments 2023™
Radon and Vapor Intrusion Symposium

Welcome to Indoor Environments 2023™, Radon and Vapor Intrusion Symposium, formerly the AARST International Radon and Vapor Intrusion Symposium.

AARST 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 AARST grows, the symposium also grows the range of attendees and vendors. Many are attendees are technicians in the field of radon and vapor intrusion measurement and remediation, and increasingly more environmental companies attend for training and to expand their forums. Additionally, states, tribes, and territories are now counted as part of the attendee body and have a dedicated concurrent track in the agenda for the entire symposium. The addition of the vapor intrusion concurrent track 3 years ago, is growing in reputation and continues to attract more attendees and new vendors. AARST leads in communication and support to the industry. As such, Indoor Environments 2023 is the definitive source for government agencies, advocates, educators, scientists, and companies sourcing field application-based needs seeking the leading indoor environments gathering annually.

Information for exhibitors and sponsors at Indoor Environments 2023™

Exhibitors and sponsors should pre-register with AARST in order to purchase booth(s) and sponsorships. All booth and sponsorship selections are purchased based on a priority point system. Priority exhibitors have the opportunity to purchase before others. (Details below)

Priority List and Purchasing

Exhibitors with 15.1 points or more are listed on the Priority List annually. Exhibitors with the highest number of points select first during pre-determined selection dates. In order to qualify for placement on the Priority List annually, exhibitors must be AARST members in good standing. Once the Priority List selection period has ended all other vendors with 15 points and less 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 (4 until 2024). The 2023 points listed below are calculated from 2022 + 2021 + 2020 + 2019. (2020 equals “0”) 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.

The Priority List (below) represents four years of accrued points (which includes 2020 as “0”, which will drop off by 2024.)

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 next week. Priority Selection period is April 10 – May 19. After May 19th all remaining booths and sponsorships are available to purchase on a first come first serve 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.
