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 radioactive gas that is found naturally throughout our environment. It is produced by the decay of uranium found in rocks and soil. Since radon is a gas, it can move freely through the soil enabling it to escape into the atmosphere or seep into buildings.rom the data, it can be seen that there are several regions of the country where indoor radon is more prevalent. The current estimate of the percentage of Canadians living in homes above the 200 Bq/m 3 guideline, based on the completed two-year dataset, is 6.9%.
