Across
  1. 6. any amount of energy emitted
  2. 8. part of a power plant, releases excess heat to cool down the reactor.
  3. 9. located in Japan,was too close to the ocean,Tsunami caused people to evacuate, leading to the reactor not getting cooled down.
  4. 10. nuclear core becomes so hot it melts, including the floor of vessel.
  5. 12. combination of symptoms that occur after a fallout
  6. 14. 3% of radioactive material, highly radioactive, EX: fuel rods
  7. 15. strips electrons from atoms, creating ions
  8. 17. one atom splitting into two
  9. 21. 30km(~20mi) radius around Chernobyl, unhabited by humanity
  10. 22. absorbs neutrons, raises and lowers reaction rate
  11. 23. high energy radioactive particles
  12. 24. trigger fission in neighboring atoms
Down
  1. 1. radioactive material that is put into the atmosphere after a nuclear blast
  2. 2. an agreement of nations to not test nuclear, besides underground
  3. 3. adds a proton, gets rid of a electron and neutron
  4. 4. creates a helium atom from pre-existing atom
  5. 5. atoms joining together in a nuclear reaction
  6. 7. given amount of time needed for half of a radioactive atom to decy
  7. 10. liquid, useally water, that pumps heat away from the fuel rods
  8. 11. what was the cause of Three-mile island's partial meltdown?
  9. 13. the worst nuclear disaster as of today, located in Ukraine
  10. 16. two atoms joining together
  11. 18. Atoms with the same number of protons but different numbers of neutrons
  12. 19. an immensely powerful bomb whose destructive power comes from the rapid release of energy during the nuclear fusion of isotopes of hydrogen (deuterium and tritium), using an atom bomb as a trigger.
  13. 20. 90% of radioactive material level, slightly radioactive, EX: hazmat suits
