Specimen Section 2

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

signal while minimizing space-charge effects. The ion trap is typically filled with helium to a pressure of about 1 mtorr. 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
