The 2024 Indoor Environments Radon and Vapor Intrusion Symposium has ended. Thank you to all the attendees who came! We hope you made new connections - and plan to attend next year in Fort Worth Texas.

The symposium has educational opportunities for all attendees, beginning with Sunday short courses (at extra fees), and Monday, Tuesday, and Wednesday continuing education (included in the price of registration).

The annual symposium is a great opportunity to earn continuing education credit for certifications. Most states and agencies accept the Indoor Environments Symposium credits attendees can earn for free Monday – Wednesday. (daily quizzes – online, completion certificates available immediately after passing each quiz).

Attendees may attend any session on all days, in any concurrent track. Simply keep track of your quiz answers using workbooks distributed daily. The online quiz is available daily.  

In addition, Indoor Environments offers continuing education courses on Sundays pre-symposium. These courses are hosted by IEA and bring in the most in-demand and often unique courses trainers are developing just for the symposium. Trainers run their courses and distribute all students’ course completion certificates for Sunday courses.

Conducting Radon Surveys in Schools: Course ID# CERTI-330 6 Hours / 6 Cat-I Credits

Description:  Conducting a radon survey in a school is a little different than testing a home. In addition to the thermal stack effect, a building’s heating ventilation, and air conditioning system (HVAC) complicates the situation by reducing indoor radon or increasing it if it is improperly maintained. Add to that varying operating conditions that exist when a building is occupied versus unoccupied make the interpretation of measurements an interesting, but not overwhelming challenge -if done correctly.

This course walks through the unique considerations presented by schools as well as a commercial building that has central HVAC systems. A student completing this course should be able to:

Plan a radon survey
Implement a communication plan for staff and parents
Be able to place and retrieve devices
Implement a quality assurance and quality control plan
Interpret the results and determine appropriate follow-up action
Develop an initial response plan should elevated levels be found.
This course is designed for radon professionals who wish to conduct radon surveys as well as building managers who may be charged with overseeing such a survey.
