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.
It exists in both natural and man-made forms and has many beneficial uses, including x-rays and the generation of electrical power. Radon is a natural form of radiation that can cause serious health problems and is often found in igneous rock and soil. An odorless, colorless radioactive gas, radon is estimated to be the second leading cause of lung cancer in the United States, responsible for over 20,000 estimated lung cancer deaths each year.
