Reprinted with permission from "Atomic Radiation," O 1957 by RCA Service Co, Inc because the radiation-producing effect is interrupted. Radioactive materials, on the other hand, have the property of spontane*. ously emitting radiation (such as alpha, beta, or gamma radiation) continually at a rate which is characteristic of the radio nuclides which make up the radioactive component of the material. Such materials may, of course, be pure radionuclides. A radionuclide is chemically identical
