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.
Radon is a colourless, odorless, radioactive gas that occurs naturally in the environment. It comes from the natural breakdown of uranium in soils and rocks. It seeps out of the ground, into basements and moves to other areas of a building or home.Radon gas can move through small spaces in the soil and rock upon which a house is built.It can seep into a home through dirt floors, cracks in concrete, sumps, joints, basement drains, etc. Concrete-block walls are particularly porous to radon.adon gas exists in many areas of Ontario at different levels. Some areas of Ottawa can contain higher than acceptable levels. While one house may have safe levels, the house next door may not. Testing must be performed in order to determine the levels in a particular home.
