How Radon Affects You in the Summertime
When most people think about summer home concerns, they think about heat, humidity, and higher energy bills. Radon usually isn’t at the top of the list. However, radon exposure remains a year-round health concern, and summer conditions can affect how radon enters and behaves inside your home.
What Is Radon?
Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It can enter homes through cracks in foundations, gaps around pipes, crawl spaces, and other openings.
Because radon is colorless, odorless, and tasteless, the only way to know your home’s radon level is through testing.
Why Summer Doesn’t Eliminate Radon Risk
Many homeowners assume radon is primarily a winter problem because homes are sealed up tighter during cold weather. While radon levels can sometimes be higher in winter, radon remains a concern during the summer months as well.
Several summer factors can influence radon levels:
1. Air Conditioning Creates Pressure Changes
When your air conditioner runs, it can create slight pressure differences inside the home. In some cases, this may draw soil gases, including radon, into the house through foundation openings.
2. Hot, Dry Weather Affects Soil
Extended periods of heat can dry out the soil around your home. As soil shrinks and cracks, it may create additional pathways for radon to move toward the foundation.
3. Closed Windows and Doors
Even during summer, many homes remain closed up while air conditioning is running. This can reduce natural ventilation and allow radon to accumulate indoors.
How Radon Affects Your Health
The biggest concern with radon is long-term exposure. When radon breaks down, it produces radioactive particles that can be inhaled into the lungs.
Over time, these particles can damage lung tissue and increase the risk of Lung Cancer.
According to the U.S. Environmental Protection Agency (EPA):
- Radon is the second leading cause of lung cancer in the United States.
- It is the leading cause of lung cancer among non-smokers.
- Thousands of lung cancer deaths each year are attributed to radon exposure.
Signs of Radon Exposure
Unfortunately, radon exposure does not cause immediate symptoms. You won’t feel sick after a few days or weeks of exposure. The health effects typically develop after many years.
That is why testing is so important.
Should You Test in the Summer?
Yes. Summer is an excellent time to test your home for radon.
Testing during different seasons can provide a more complete picture of your home’s radon levels. If you’ve never tested your home, there is no reason to wait until winter.
Consider testing if:
- You’ve never tested your home.
- You’re buying or selling a house.
- You recently finished a basement.
- You’ve made foundation or HVAC changes.
- It’s been several years since your last test.
What Happens If Levels Are High?
If testing shows elevated radon levels, a professional mitigation system can significantly reduce the amount of radon entering your home.
Most systems work by creating negative pressure beneath the foundation and venting radon safely outside.
In many cases, mitigation can reduce radon levels by 80% to 99%.
Protect Your Home Year-Round
Radon is not just a winter issue. Summer conditions can still allow radon to enter and accumulate inside your home, making year-round awareness important.
Because radon is invisible and has no immediate symptoms, testing is the only way to know whether your family is being exposed.
If you haven’t tested your home recently, summer is a great time to take that step and gain peace of mind.
