Practice Problem 27-8 The Dead Sea Scrolls, a collection of texts written mostly on
dried animal skins, were found in caves along the northwest shore of the Dead Sea
in the late 1940s and 1950s. Carbon-14 dating indicates that the scrolls were writ-

Gamma Radiation
A nucleus in an excited state radiates energy in a way analogous to the emission of
an x ray when an electron in an excited atomic state falls to a state of lower energy.
The most common way that a nucleus can become excited is following an a or 3
decay. Although the a and3 decay processes result in a more stable configuration of
the nucleons, the nucleons that remain in the daughter nucleus may not be, initially,
in the most stable arrangement for that particularnuclide This evcirelcate decys
