Those particles usually come from decaying matter in soil and rocks.</p></div>

Q: What types of radon mitigation systems are available?

Q: How long does a radon mitigation system last?

• <div><p>The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades.
