Across
  1. 3. A nuclear reaction where the fission process rapidly continues without any control, causing a large amount of energy to be released almost instantaneously.
  2. 7. The reaction in which small nuclei are forced together by extreme heat and pressure to form a larger nuclei.
  3. 9. A type of radioactive decay that releases a beta particle.
  4. 12. The radioactive material that falls to Earth after a nuclear explosion.
  5. 13. A nuclear reaction where the rate of fission is carefully managed, allowing for a sustained release of energy at a controlled level.
  6. 15. The type of radioactive decay that releases energy from an excited nucleus in order to change its energy state.
  7. 18. The spontaneous nuclear transformation of an atom.
  8. 19. The most common fuel used in nuclear reactors.
  9. 21. The emission of particles or electromagnetic waves from an unstable nucleus.
  10. 23. A device used to detect radiation by measuring the ionization it produces in a gas.
  11. 24. The type of radioactive decay that changes a neutron into a proton and releases an electron and increases the atomic number of the atom by one.
Down
  1. 1. A fundamental particle of electromagnetic radiation and light.
  2. 2. The SI unit for radiation.
  3. 4. The product of a reaction is used to start another reaction.
  4. 5. The reaction where a large unstable nucleus is struck by a neutron and splits into smaller nuclei.
  5. 6. A process in which the structure of an atomic nucleus is altered through release of energy or mass or by being broken apart.
  6. 8. The type of Radioactive decay that changes a proton into a neutron and releases a positron and decreases the atomic number of the atom by one.
  7. 9. An electron or Positron
  8. 10. A type of radioactive decay that releases an Alpha particle.
  9. 11. A device used to initiate and control a fission nuclear chain reaction.
  10. 14. The use of sustained nuclear fission to generate light and heat.
  11. 16. A particle that is released during radioactive decay that consists of two protons and two neutrons (Helium Nucleus)
  12. 17. A high-energy photon
  13. 20. a byproduct of nuclear reactors, fuel processing plants, hospitals, and research facilities.
  14. 22. The site of the worst nuclear disaster in history.
