The gaseous element radon gets attention largely because it is radioactive. Radon is the heaviest and only radioactive member of the group of elements called the noble or inert gases. It was discovered around 1900, and for years, many people thought it had health benefits and intentionally exposed them to it. Now it is known as one of the principal causes of lung cancer. Readers will investigate radon, its atomic structure, and its place on the periodic table. Explore the process of radioactive decay and learn about the many uses and dangers of radon, as well as take steps to reduce radon concentrations in the home. Includes full-color and black and white pictures, glossary, bibliography, index, periodic table of elements, further reading, more information. 5 chapters, 48 pages.
