Ionizing radiation can come from unstable (radioactive) atoms or it can be produced by machines. As unstable atoms decay and attempt to become stable, the nuclei release energy in the form of ionizing radiation (alpha particles, beta particles and gamma rays). WebAn atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons. What is meant by stable configuration? do all nonprofits need a board of directors
