Radon is a radioactive gas created when uranium in the ground decays. Unfortunately, Utah has high levels of uranium, which means there’s an increased risk for radon exposure in the state. This is not a problem to be taken lightly. Although radon doesn’t pose a great threat outdoors, if it gets trapped inside your home and concentrates, it can cause lung cancer. What homes need a radon mitigation system?

There’s a common misunderstanding that only old homes need radon mitigation systems, but it’s not that simple. We’re here to help you understand if your home should have a radon mitigation system installed.

Homes with high radon levels

Radon can’t be detected by our senses, and the only way to know if your home has a high radon level is to test for it. All Utah residents can get a free radon test here!

The World Health Organization recommends mitigation at 2.7 pCi/L, and the Environmental Protection Agency recommends considering mitigation at 2.0 pCi/L. If you spend a lot of time on the lowest level of your home, you should be more concerned at lower levels than if you have an empty basement that never gets used. Regardless, one thing is true: No matter how old your home is, it should be mitigated if it has high radon levels.

Radon systems in new homes

Radon levels are directly related to the amount of uranium in the soil. Because of this, radon doesn’t discriminate between old and new homes. However, when a home is being built, a radon mitigation system can be installed during the construction process as a proactive measure. This not only keeps your loved ones safe from radon but can be a financially savvy decision, as it can be much less expensive than installing a system after radon has already been concentrated inside.

Radon systems in old homes

Radon seeps into buildings through cracks and pores in the home’s foundation. While old homes aren’t always guaranteed to let more radon in, the more they age, experience weather, and have structural changes, the more radon they may let in. No matter how old your home is, you should test it for radon every two years to ensure radon isn’t rising to high levels. One in three homes need a radon mitigation system.
