January is National Radon Action Month

January is a time to raise awareness about the dangers of radon and how to protect yourself and your loved ones from this silent killer. If you’ve never heard of radon, you’re not alone. Many people are unaware of this radioactive gas, but it is important to educate yourself and others about radon because it can pose serious health consequences.

What is Radon?

Radon is a naturally occurring gas that forms from the breakdown of uranium in the rock, soil, and water beneath your home. Radon can become trapped indoors after it enters through porous materials or cracks in your foundation. When inhaled, the gas can damage the cells lining the lungs, increasing the risk of lung cancer. In fact, radon is the second leading cause of lung cancer in the United States, responsible for an estimated 21,000 deaths each year.

The Importance of Testing for Radon

Testing is your best defense against this radioactive and silent killer. The scary thing about radon is that it has no smell, taste, or color, so you can’t see, smell, or taste it. This means that you could be breathing in unsafe levels of radon without even knowing.

It is important to test your home for radon to determine if it is present and at what levels. The good news is that radon can be easily detected and mitigated. The first step is to have your home tested for radon. This can be done with an easy-to-use and inexpensive kit.

What If My Home Tests High for Radon?

If the test results show that radon levels are high, it is important to take action to reduce them. This can be done through the use of a radon mitigation system, which uses a series of pipes and a fan to vent the gas out of your home and minimize radon to safe levels. A certified radon professional can also determine if sealing and other preventative measures are necessary.

Are test results from my next-door neighbor’s house an accurate indication of radon levels in my home?

Several factors can affect the presence and levels of radon in a home. These include the permeability of the ground and the composition of the soil, as well as the construction of the home itself. Each home is unique in these regards, and radon levels can vary widely from home to home. The only way to know if you have it in your home is to test.

If my home was just recently built, is it really necessary to test for radon?

Radon can be found in all types of homes—new and old homes, well-insulated and drafty homes, and homes with and without basements. The best way to know is to test and see the results.

If I test for radon and the results indicate high levels, will it reduce the value of my home?

Radon can be a concern for potential homebuyers, but if the issue has been addressed and resolved through measures such as a radon mitigation system, it can increase the value of the home. Some real estate agents believe that a resolved radon issue has a neutral or positive impact on the ability to sell a home.
