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.
A: Radon is an odorless radioactive gas that results from the breakdown of uranium. Uranium is present in most of the soil and rock around the world. It is typically concentrated in areas with lots of granite, shale, phosphate and pitchblende.: Because radon is a gas, it can leak into your house through the basement or crawl space--via adjacent or exposed soil and rock--or through well water.
