Submissions that do not adhere to the instructions will be returned for editing.

Technical and Educational Scope

Scope: Presentations should consist of, but are not limited to new original research, (suggested categories listed below) empirical or applied, on radon and vapor intrusion risk, radon and vapor intrusion measurement, radon and vapor intrusion mitigation, soil gas controls in new construction, analytics, risk communication, and similar topics are encouraged, including abstracts from related scientific, engineering and health-related disciplines. We also welcome presentations on effective methods of conveying essential radon and vapor intrusion messages to target audiences, reducing risk for low-income families, marketing and expanding radon and vapor intrusion professional services, enacting and implementing new public policy, demonstrating radon and vapor intrusion technology, and similar activities to further the radon and vapor intrusion professions and transfer of information. Submissions are welcome on all relevant topics. 

IEA is committed to meaningful and impactful discussions and outcomes, and it is crucial to ensure that the topics selected during the review process focus on align with IEA goals and interests. Our aim should be to engage with topics that not only resonate with our immediate professional environment but also contribute meaningfully to broader conversations in our field. Consider the following key tenents when submitting:

Relevance to Our Industry:
Does the topic directly relate to our industry’s current trends, challenges, or future directions?
How will exploring this topic benefit our industry or contribute to professional practices within it?

General Relevance:
Is the topic of significance in the broader context beyond our immediate industry?
Could this topic have implications or applications in other fields or sectors?

Interest Level:
Will the topic engage and captivate the interest of our workgroup members and our wider audience?
Does it provoke curiosity or bring a fresh perspective to known issues?

Defensibility of the Premise:
Is the topic’s premise supported by data, research, or credible observations?
Can the topic withstand critical scrutiny and spark constructive debate?
