radon gas

Radon gas is a naturally-occurring gas that can be found in the air, soil, and even the water we drink. It can cause some health risks when the levels are too high, because it's a radioactive gas and it can damage the cells in your body. The best way to protect yourself from radon gas is to have your home tested to make sure it is safe. The test will tell you if there is a high level of radon in your home. If your home tests positive, you can have it fixed to reduce the radon levels.
