14.4 Concentration Changes over TimeReaction Half-Life
Nitrogen-13 is used in tracers injected into the bloodstream forpositron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. How much time is required for the mass of a sample of nitrogen-13 to fall to 6.25 percent of its original value? Since the decomposition is a radioactive decay reaction, it is first order.
