Health Risks of Radon Exposure - Radon is a natural radioactive gas that comes from the breakdown of uranium in soil and rock. You cannot see it, smell it, or taste it. That is what makes it risky. Radon can move through the ground and slip into a home through cracks in the foundation, gaps around pipes, sump pumps, crawl spaces, and even well water. Once inside, it can build up to unsafe levels, especially in basements and lower floors.
Why radon is a health risk
When you breathe in air that contains radon, the gas breaks down into tiny radioactive particles. Those particles can get trapped in your lungs. Over time, they give off radiation that can damage lung tissue. Like sunburn can hurt your skin, radon can slowly injure your lungs from the inside. This damage can raise the chance of developing lung cancer.
Radon is the second leading cause of lung cancer overall, after smoking. It is the leading cause of lung cancer for people who do not smoke. The risk is much higher if someone smokes and the home also has high radon levels. Smoke already irritates and harms the lungs, and radon adds more damage. That is why families should care about radon even if nobody smokes, and why it is especially important if anyone in the home does.
Who can be affected
Radon does not only affect adults. Children can be exposed too. Kids breathe faster than adults and may spend a lot of time playing on the floor or in finished basements. Any long-term exposure can matter, because cancer risk often grows with years of breathing radon.
It is also important to know that radon problems are not limited to old houses or “run-down” buildings. New homes can have high radon levels too. A home can look clean, modern, and well built, and still have radon.
Common myths
- “If my neighbor’s house is fine, mine is fine.” Radon levels can change a lot from house to house, even on the same street.
- “I have good ventilation, so I’m safe.” Some airflow helps, but it does not guarantee radon stays low.
- “Radon is only a basement issue.” Basements are often the highest, but radon can reach any level of a home.
The good news: you can test and fix it
Testing is the only way to know your home’s radon level. Radon tests are simple and affordable. You can use a short-term test (often a few days) to get a quick reading, or a long-term test (months) for a more accurate average. If the results are high, a qualified radon professional can install a mitigation system. These systems usually vent radon from under the house and release it safely outside. Many fixes can be done in a day, and they can greatly lower radon levels.
What every family should do
- Test your home for radon, even if you have never had problems.
- Retest after major changes, like finishing a basement, sealing floors, or replacing heating and cooling systems.
- If levels are high, take action quickly. Mitigation works.
Radon is a hidden hazard, but it is also a preventable one. A simple test can protect your family’s health for years to come.
