6 EQUATIONS OF RADIOACTIVE DECAY AND GROWTH

6.6 RADIOACTIVE DECAY SERIES If a radioactive nuclide is situated in the Chart of Nuclides far from the stability line (for the light elements at Z=N), the daughter nucleus after radioactive decay may be radioactive as well. In nature this occurs with the heavy nuclides in the uranium and thorium decay series (Chapter 12).

A radioactive isotope X, which is used in hospitals, has a half-life of 6.0 hours. It decays to form an isotope Y of a different element which is not radioactive. A pure sample of X is produced in a nuclear reactor. Twelve hours later, when the sample arrives at a hospital, the number of atoms of X in the sample is 1.6 × 10

Collisions with helium dampen the kinetic energy of the ions and serve to quickly focus trajectories toward the center of the ion trap, enabling trapping of injected ions. Ion traps are unique in
