Why are radioisotopes that emit low energy (100–250 keV) gamma rays preferred for the diagnostic procedures of nuclear medicine? Because: 

  1. high energy gamma rays are too easily stopped by body tissue
  2. radioisotopes that emit gammas within this energy range have a half-life that is ideal for diagnostic procedures
  3. photons of this energy are sufficiently penetrating to escape from the body but are able to be detected
  4. charged particles are too difficult to shield against

C: There is a trade off where the photons should be penetrating enough so that they are not stopped within the body, but not so penetrating that too few are stopped by the detector placed next to the body. This energy range satisfies both needs.
