Radioactive decay is a spontaneous process wherein unstable nuclei emit ionizing radiation in three distinct modes: alpha particles (helium-4 ions), beta particles (high-speed electrons or positrons), and gamma rays (electromagnetic photons). These emissions are differentiated by their intrinsic properties, including mass-to-charge ratios, kinetic velocities, penetrating capabilities through matter shielding, and relative ionization potentials within an electrostatic field. This phenomenon constitutes a fundamental sub-discipline of nuclear physics, governed by the conservation laws of energy and momentum that dictate the specific trajectories and interactions of these radiations with external fields and material barriers.
