Long-term Effects of Radon Exposure on Children’s Health

Radon is a natural gas that comes from the breakdown of uranium in soil and rock. You can’t see it, smell it, or taste it. It can move up through the ground and slip into a home through small cracks in a basement floor, crawl space, or even around pipes. Outdoors, radon usually spreads out and is not a big problem. Indoors, it can build up to unsafe levels.

 

When you breathe radon, you also breathe tiny radioactive particles. Over time, those particles can damage cells in the lungs. The body can repair some damage, but repeated exposure makes it more likely that harmful changes stay in the cells. Years later, those changes can lead to lung cancer.

Radon is the second leading cause of lung cancer after smoking. Even people who have never smoked can be affected. For people who do smoke, radon exposure raises risk even more.

 

Children are still growing, and their bodies are building new cells quickly. Fast-growing tissues can be more sensitive to damage. Children also breathe faster than adults, which can mean they take in more air (and more radon particles) compared to their body size.

Children also have more years ahead of them. That matters because radon-related lung cancer usually develops after long-term exposure and a long “latency period” (the time between exposure and disease). If a child is exposed early in life, there is simply more time for health effects to appear later.

 

The main long-term health concern linked to radon is lung cancer. Radon does not usually cause immediate symptoms. That’s one reason it can be so dangerous: families may live with high radon levels for years without knowing.

Some people worry about radon causing other illnesses. Researchers continue to study this, but the strongest and most proven link is to lung cancer. The good news is that radon risk can be reduced.

 

Radon can enter through:

Testing is simple and affordable. Short-term tests can give a quick snapshot, while long-term tests can show average exposure over time. If levels are high, radon mitigation systems can vent radon from beneath the home and reduce indoor levels.

 

Because radon has no smell and no warning signs, testing is the smartest first step—especially for families with children. If you haven’t tested your home (or it’s been a few years), consider doing it today.
