Radon is one of the most misunderstood hazards found in homes. During Radon Action Month, we often hear the same myths that cause homeowners and buyers to skip testing altogether. The truth is, radon is common, invisible, and easy to test for when you know the facts.

Let’s clear up the top five myths about radon testing.

Myth #1: Radon Is Rare, So I Do Not Need to Test

The truth:Radon is very common, especially in Indiana. The EPA estimates that 1 in 15 homes in the U.S. has elevated radon levels, and Indiana is considered a high radon state.

Radon comes from the natural breakdown of uranium in soil. It can be found in homes of any age, size, or location. The only way to know if your home has elevated levels is to test.

Myth #2: New or Newly Built Homes Do Not Have Radon

The truth:New construction does not protect a home from radon. In fact, newer homes can sometimes have higher radon levels because they are built more tightly and trap gases more efficiently. Radon enters through cracks in foundations, sump pits, and utility penetrations. Even brand new homes should be tested.

Myth #3: Radon Is Only a Problem If You Have a Basement

The truth:While basements are common entry points, radon can affect any home, including slab-on-grade homes and homes with crawl spaces. Radon testing is performed at the lowest livable level of the home, whether that is a basement or a first floor. You do not need a basement for radon to be an issue.

Myth #4: A Neighbor’s Test Means My Home Is Safe

The truth:Radon levels can vary drastically from one home to the next, even if they are right next door to each other. Soil conditions, foundation type, and construction details all affect radon levels. A neighbor’s results do not provide any information about your home.

Myth #5: Radon Testing Is Complicated and Expensive

The truth:Radon testing is simple, affordable, and non-invasive when done by a professional.

Most radon tests run for 48 hours and do not disrupt daily life. If elevated levels are found, mitigation systems are proven to be effective and typically cost far less than most people expect.

Why Radon Testing Matters

Radon is the second leading cause of lung cancer in the United States and the leading cause among non-smokers. Because radon is colorless and odorless, testing is the only way to protect your home and your health.

January is the ideal time to test due to closed-home conditions, making Radon Action Month the perfect reminder to take action.
