Understanding Radon Gas

by Murray Anderson

Radon gas seems to be one of those things that is a mystery to many homeowners. We’ve all heard of it but there’s lots of confusion about what Radon is, if it’s really dangerous and how to find out if there is any Radon in your home. To answer some of those questions, here’s a quick primer on Radon Gas and your home.

What is Radon?

Radon is n gas that occurs naturally in the environment as a result of the decomposition of uranium. Small traces of uranium are found in almost all rocks and soil everywhere in the country so radon gas itself is always around us in very small quantities in the air in the air we breathe. However, since radon is colorless, odorless and tasteless it’s undetectable to humans.

If it’s a natural element, why should I be concerned about it?

According to the Environmental Protection Agency, radon is classified as a human carcinogen and breathing radon has been scientifically linked to an increased risk of lung cancer particularly for smokers. The higher the concentration of radon in the air, the higher the risk, so while traces of radon in the atmosphere may not be a concern, a radon build up in your home is definitely something to be concerned about.

How does Radon get into my home?

Radon gas can get into a home in a number of ways. As a gas, radon moves through the ground around your foundation and it can come into your basement through any cracks in the foundation. Radon can also be dissolved in ground water be carried into your home along with your water supply. Homes that use well water rather than municipal water supplies are particularly prone to radon entry in this way.

How can I tell if radon is in my home?

The quickest way to get a radon testing kit (short-term kit) available at home and hardware stores or on line. Since radon levels in your home can fluctuate during the year, a short-term test isn’t necessarily the definitive way to test for Radon, it will give you an indicator as to whether you may have a Radon problem. If the results of your first short term indicate excessive radon another short-term test or even a long-term test (where the sensor stays in place for 90 days or more) will provide a truer picture.

How do I actually use a test kit in my home?

While all the test kits are slightly different and you should follow the specific direction on the kit you choose, the process typically involves placing the test kit on the lowest level of your home that is used regularly. It could be in the basement or on the main floor, just not in the kitchen or a bathroom. You leave the kit in place for 2 to 3 days then seal it up and send it to the location identified on the package for testing. You should get your results back in two to three weeks.
