Gamma rays are produced when?
- A. high velocity electrons are abruptly stopped in metals
- B. energy changes occur within the nuclei of atoms
- C. energy changes occur within the electronic structure of atoms
- D. electrons are deflected in very strong magnetic fields
Correct Answer: B. energy changes occur within the nuclei of atoms
Explanation
Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. Gamma radiation is emitted by excited nuclei or other processes involving subatomic particles; it often accompanies alpha or beta radiation, as a nucleus emitting those particles may be left in an excited (higher-energy) state.
