The proposed session would provide an in-depth introduction to two recently published American National Standards Institute/American Association of Radon Scientists and Technologists (ANSI/AARST) building standards related to radon resistant new construction techniques. The two standards are the CCAH-2020 w/5/23 revisions Reducing Radon in New Construction of 1 and 2 Family Dwellings and Townhouses and the CC-1000 w/5/23 revisions Soil Gas Control Systems in New Construction of Multifamily, School, Commercial and Mixed-Use Buildings.
The session will provide participants with a basic understanding of the construction elements and practices related to installed at construction passive radon control systems for both residential and non-residential buildings. The session will also discuss post-build radon testing and potential activation requirements for buildings with passive radon controls that still test for elevated radon levels.
Learning Objectives:
By attending this session, attendees will:
understand how buildings can be built with passive radon control systems
use the relevant national standard for designing passive radon control systems for buildings
recognize the differences between small-scale residential and large building passive radon control systems
