Across
  1. 5. dose, Measures the amount of radiation absorbed per unit mass of matter (gray "Gy")
  2. 6. Anode, Method of dissipating heat in general purpose X-ray tubes which must be capable of producing high intensity X-ray beams in a short time
  3. 8. effect, Noticeable short term effects due to, rarely, from diagnostic imaging setting
  4. 9. The smallest particle of substance, arranged in the periodic table
  5. 13. Spectrum, Two types of energy used in X-ray are Electrical energy and electromagnetism
  6. 15. The smallest particle of an element
  7. 16. A material (concrete or lead) which absorbs radiation or prevents the transmission of radiation to the wearer
  8. 17. Heel Effect, Has a greater intensity on the side of the cathode and diminishing toward the anode side
  9. 19. The smallest quantity of any type of electromagnetic radiation
  10. 20. The study of radiographic images of any and all imaging disciplines
  11. 21. Length of the space between two points and helps prevent unnecessary radiation
  12. 22. Any substance that has mass and takes up space
  13. 26. The unit used to measure tube current (mA)
  14. 28. The distance between two successive crests or troughs
  15. 29. Two filaments that are large and small are made of this metal
Down
  1. 1. effect, Occur by chance and my occur without a threshold level of dose. Late term effects.
  2. 2. Emission, The process of heat supplied to the cathode resulting in electrons energized off the cathode filament
  3. 3. Energy Transfer, All types of radiation have the ability to penetrate tissue and transfer energy
  4. 4. decay, Process when an atom spontaneously emits particles and energy due to being unstable
  5. 7. A negatively charged electrode within the X-ray tube
  6. 10. No charge in the atom
  7. 11. The number of waves passing a given point per given unit of time
  8. 12. equivalent, Measured by the dosimeter worn by personnel exposed to radiographs (Sievert "Sy")
  9. 14. Used to hold film for film X-rays
  10. 18. Device that is used to measure X-ray exposure
  11. 19. Positives charge in the atom
  12. 23. A positively charged electrode within the X-ray tube
  13. 24. Exposure refers to two different occurrences, Exposure Rate and Exposure Time
  14. 25. radiation, Dose measured by the service personnel calibrating the X-ray unit (air kerma "Gya)
  15. 27. Negative charge in the atom
