One way is to seal cracks and openings in the foundation, walls, and floors. Another way is to install a radon mitigation system. Radon mitigation systems remove radon from the air before it can enter the home.<\/p>\n<p>If you are concerned about radon in your home, you can test the air for radon. Radon testing kits are available at most hardware stores. If you find that your home has high levels of radon, you should take steps to reduce the levels.<\/p>\n<p>Thorium, radium, and plutonium are also radioactive elements, but they are not as common as radon.
