Many people have never heard of radon, or if they are aware of it, they have not tested their home for it. Only smoking causes more lung cancer deaths. If you smoke and your home has elevated radon levels, your risk of lung cancer is even greater. It s a matter of testing your home and taking steps to remediate, if necessary.
Radon is a decay by-product of radium.
Radium is present in low concentrations in most soils and rocks. It is a colorless, odorless, tasteless, radioactive gas. You can't see it, smell it, or taste it. Radon lasts for several days before it begins to break down. It has a half-life of 3.8 days.
