So you’ve tested your home for radon and your home tested below the recommended action levels. These action levels are meant to be guidelines in helping you decide whether you need to install a system or not. Anything over a level of 4 should have immediate action taken according to the EPA. Anything between 2.7 and 4 is recommended by the WHO. But, how long do radon test results last for?

If you tested below those levels, you will probably choose not to install a system at this time. Although some people do choose to install a system as a preventative measure.

So if your levels are low today, will they ALWAYS remain low?

The Environmental Protection Agency (EPA) doesn’t have a specific length of time that test results are considered valid. However, they do make the recommendation of testing every two years. This is because conditions in the soil below the house can change resulting in higher levels of radon developing. Also, the foundation can develop cracks, which can allow more radon into the home.

Because radon is colorless, odorless and tasteless you will not know if your radon levels begin to climb unless you retest your home. Because the risk of lung cancer increases the longer you are exposed to radon gas, you should follow the EPA recommendation of having your home tested every two year.

Should you retest your home if you have a radon system?

If you have a radon system installed in your home, it is still recommended that you test every two years. This is for the same reason and to make sure that your radon mitigation system is functioning properly.
