Vendor Prospectus

Symposium Section

The AARST International Symposium offers the opportunity to connect with mitigators, industry leaders, as well as other vendors. A great time to build relationships with people just joining the industry, as well as seeing old friends and growing those relationships, as an exhibitor, we get the chance to highlight products and learn what is going on in the industry to better serve our customers. The AARST show is where the best, brightest, and innovative minds come together to better the radon industry. We are proud to be a vendor each year! – Crystal Lytle, Fantech

Join us to celebrate our 35th anniversary supporting the industry and Radon Professionals Saving Lives. The symposium will be held at the Bethesda North Marriott Hotel & Conference Center at 5701 Marinelli Road, Rockville, Maryland.

Priority List and Purchasing

Vendors with 15.1 points or more are listed on the Priority List annually. Vendors with the highest number of accrued points select first during pre-determined selection dates. Once the Priority List selection period has expired all other selections for vendors with 15 points and less will be assigned based on availability and first come first serve.

All points accrued during the season will calculate on each vendor dashboard. All items have points assigned to them.

The Priority List (Below) represents three years of accrued points but does not include 2020 where no points were earned. The point system is based on how many points are earned with every eligible purchase.

Eligible Points which make up the Point System and generates the Priority list each year works as follows:

  • Booth = 1 point per every $200 of the cost of the booth
  • Purchase any Sponsorship and/or Advertisement = 1 point per every $200
  • Points accrue over the 3 most recent consecutive years. Older points drop from the accrual formula. For example: 2021 Points below are points earned from 2019+2018+2017. (2020 equals “0”) If vendors have not exhibited or sponsored in those 3 years that particular year = “0”.

Vendors will be assigned to a week to select:

At the end of each selection period, those vendors will be assigned the spaces and items, all availability updated for the start of the next set of selections. Selection period is June 14 through July 5. All vendors remaining may purchase beginning July 6th.

Pre-requisite to purchase Premium Sponsor Packages: Purchasing 1 (minimum) booth entitles you to purchase the following Premium Sponsor Packages: Diamond, Platinum, Gold. Your booth must be purchased first – to open sponsor packages in the store, available exclusively to booth holders.

Choosing your booth: The booth store has options in check out for 1st, 2nd and 3rd choices for booths. Choices are ranges in rows or specific large booth numbers.
