Design and Construction of Radon-Resistant Homes

COURSE NO: C04-012
COURSE PROVIDER: Brian McCaffrey, P.E.
Design and Construction of Radon-Resistant Homes
Course Highlights

This online engineering PDH course will provide step-by-step guidance on how to design and build radon-resistant homes.  By using a handful of simple building practices and common materials, radon levels in homes can be effectively reduced.  A basic radon reduction system can reduce radon levels by an average of 50% and further reductions can be accomplished with a minor upgrade to this system.


Radon is a colorless, odorless, radioactive gas that can be drawn into a building or home and accumulate to high levels.  Every building or home has the potential for elevated levels of radon, and this potential depends upon your locality.  Reducing the level of radon in homes is important because the risk of developing radon-induced lung cancer increases as your exposure to radon gas increases.


This 4 PDH online course is applicable to engineers and architects who are involved with the design or construction of residential structures.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding how radon is formed
  • Understanding of how radon enters a home
  • Knowing the action levels for radon in homes
  • Awareness of locations throughout the United States where installation of radon reduction systems are recommended
  • Designing of passive sub-slab or sub-membrane depressurization systems
  • Designing of active sub-slab or sub-membrane depressurization systems
  • Selecting the type of system to install based on foundation type
  • Understanding the various construction methods for depressurization systems
