Passive Radon Systems: Everything You Need to Know


Radon resistant new construction (RRNC) is quickly becoming a hot topic for new homes and buildings. Radon resistant new construction techniques control radon gas entry through the installation of a passive radon mitigation system. Passive radon systems can help to prevent radon gas entry without the use of a radon vent fan. These systems are more economical for consumers as the cost to install is typically less compared to retrofitting applications. Also, compared to active radon systems, there are great electrical and heat energy savings. Learn everything you need to know about passive radon systems. 

Continue to Test for Radon After a Passive Radon System Installation

Repeatedly, we have encountered instances where we visit homes to activate passive radon systems installed during the home’s construction. However, we often discover that the proper RRNC techniques were not followed. Some of the issues we find such as incorrect PVC pipe sizes, unsealed cracks, improper pipe routes, could put your house at risk of radon exposure. While this situation may pose potential risks, it’s important to note that homeowners may not be aware of these issues. They were informed that their new home comes equipped with a radon system, leading them to believe they are protected. Unfortunately, this can create a false sense of security, and many homeowners may not even test for radon gas assuming the system is functioning effectively.

Without the correct implementation of radon-resistant new construction techniques, homeowners may only have what appears to be an ineffective pipe labeled as a “radon system” in their basement. It’s crucial to address these issues to ensure the safety of residents and educate them on the importance of proper radon mitigation measures.

If you are building a new home:
  • Educate yourself about the dangers of radon gas.
  • Learn about the existing RRNC guidelines.
  • Ask your builder if they are RRNC educated.
  • Insist that a certified radon mitigation company such as Protect Environmental installs the passive radon system.
  • Document the system installation, take photos and ask questions.
  • Make certain to test the home for radon gas after the build is complete.
  • If radon levels are above the EPA recommendations activate the passive radon system with a radon fan and test again.
If you live in a home with a passive radon mitigation system:
  • Test for radon gas at least every two years.
  • Inspect your foundation for new cracks/radon entry points and seal them.
  • Call your local radon contractor to inspect the system design.
  • Do not assume that you are protected from radon if you haven’t performed a radon test.

Passive radon mitigation is a great way to reduce radon gas if the system is installed correctly. They can be easily activated if radon levels remain high and are nicely hidden within the home. These systems may help reduce lung cancer risk for you and your family but always be certain that the passive system was installed correctly and is working properly. If you need help inspecting a passive radon system or testing your home for radon, contact the licensed professionals at Protect Environmental.
