Toads can live in drier climates, where most frogs usually live in or near water. In the Tropics, where most anuran (members of the order comprising the frogs, toads, and tree toads) species occur, however, the differences are harder to determine, and some species could qualify as either toads or frogs.
Radon Gas is Found in Homes all Over the U.S. Radon is an invisible and odorless radioactive gas. Elevated levels of radon have been found in homes all across the country. Any home in any state may have a radon problem: new and old homes, well-sealed and drafty homes, and homes with or without basements. Radon gas gets into all types of buildings, including office buildings and schools.
Where is Radon Found? Radon, a radioactive gas that causes cancer, can be found in countries throughout the world. Radon becomes a problem when it is trapped in a building and becomes concentrated. There are a number of test kits commercially available to test for radon in your home. If radon is found, measures can be taken to lower the level.
