Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting ionizing radiation. The emission is described as spontaneous meaning: The nucleus decays after collision with shielding material The nucleus decays after collision with another particle or atom The nucleus decays without collision with shielding material The nucleus decays without collision with another particle or atom None 2. In isomeric transition decay, the extra energy in the nucleus is released by the emission of: Gamma photons Electrons Neutrons X-rays None 3. An alpha particle is identical to the nucleus of a helium atom. Alpha particles: Are smaller than beta particles Are used for radionuclide therapy Travel unlimited distances Are not charged None 4.
