We created this course because we found many sources for radon information to be confusing - it's easy to get lost or overwhelmed because there's so much information. We've organized this course to introduce the topic, explain how to determine if it's an issue and how to mitigate it (if needed).

The testing and mitigation (if needed) are simple and relatively inexpensive - they're nothing to fear. We think you come to the same conclusion as you complete the course.

What Is Radon?
Radon is a naturally occurring radioactive gas that can cause lung cancer. Radon is colorless and odorless so the only way to detect radon is to test for it.

All houses should be tested for radon. Thankfully, testing is simple and inexpensive. Radon mitigation systems are also inexpensive to install and operate compared to other building systems.

This course will show you how simple testing and mitigation for radon can be. There's no reason to put off testing or have anxiety about the result.
