Definition

Radon is a radioactive gas that is found in the ground. It can seep into homes and buildings through cracks in the foundation or walls. Radon is a health hazard because it can cause cancer.

Radon is invisible and odourless, so you can't see or smell it. The only way to know if you have radon in your home is to test for it.

If you have radon in your home, there are things you can do to reduce the levels. You can hire a professional to seal up cracks in your foundation and walls. You can also install a radon mitigation system, which will remove radon from the air in your home.
