  1. 2. high energy electromagnetic radiation
  2. 4. the nucleus of an atom in which the forces among its particles are balanced
  3. 6. an elementary particle with a negative electrical charge
  4. 9. a naturally occurring radioactive element whose principal isotopes are uranium-238 (U-238) and uranium-235 (U-235)
  5. 10. energy moving in the form of particles or waves
  6. 11. exposure to radiation
Down
  1. 1. electromagnetic radiation caused by deflection of electrons from their original paths, or inner orbital electrons that change their orbital levels around the atomic nucleus. X-rays, like gamma rays can travel long distances through air and most other materials
  2. 3. a combination of 2 or more atoms
  3. 5. a discrete "packet" of pure electromagnetic energy
  4. 7. a small atomic particle, typically found within an atom's nucleus, that possesses a positive electrical charge
  5. 8. the process of spontaneous transformation of the nucleus, generally with the emission of alpha or beta particles often accompanied by gamma rays
