Summary: The Realities of Radon

     In the objective science text titled "The Realities of Radon" the author focuses on the element radon and its effects on human life. First, the author describes the properties of radon. It is the heaviest known gas, highly reactive, and produced when Uranium-238, a common element found in rocks and soil, decays. Although radon is odorless, invisible, and tasteless, it is virtually everywhere.

     Next, the author informs readers of the health risks that come with radon exposure. Radon is the second-leading cause of lung cancer in the United States. It also produces a highly reactive metal called polonium that emits gamma radiation and damages the cells of the human body.

     Finally, the author concludes by reporting statistics about the risk factors of radon exposure. It is proven that only 8% of all U.S. homes suffer from radon levels exceeding the safe number of 4.0 picocuries per liter of air). Those at the highest risk are usually the buildings located on uranium-rich rock and dry soil.
