It is an invisible, odorless, tasteless gas that seeps up through the ground and diffuses into the air. In a few areas, depending on local geology, radon dissolves into ground water and can be released into the air when the water is used. fashioned into various sizes and types of sealed sources, many of which were called “needles” because of their shape.

What is Radon? Radon is a hazardous, naturally occurring gas that results from the decay of trace amounts of uranium found in the earth's crust. Odorless and invisible, radon has been classified (by the Environmental Protection Agency) as a carcinogen since 1988, and is the leading cause of cancer among nonsmokers in of the U.S.

It is produced during the radioactive decay of radium-226, itself a decay product of uranium-238 found in many types of crustal materials, that is, rocks and soils. Se hela listan på nuclear-power.net Radon (222 Rn) is released primarily from soil and approximately 10% of it is released into the atmosphere (3, 4). 218 Po, 214 Pb, and 214 Bi are radon’s most significant progeny in terms of radiation dose.
