        The Dating Game: Radioactive Carbon

        Discover how scientists can measure the presence of a radioactive form of carbon—carbon-14—in decaying remains to calculate the ages of bones, cloth, wood, and other organic matter in this media-rich essay from NOVA. The technique they use, which is effective for dating objects no more than 40,000 to 60,000 years old with a high degree of accuracy, is called radiocarbon dating.
