  2. 4. Length of the space between two points and helps prevent unnecessary radiation
  3. 7. A negatively charged electrode within the X-ray tube
  4. 8. Device that is used to measure X-ray exposure
  5. 10. dose Measures the amount of radiation absorbed per unit mass of matter (gray "Gy")
  6. 11. The smallest particle of substance, arranged in the periodic table
  7. 12. The smallest quantity of any type of electromagnetic radiation
  8. 14. A material (concrete or lead) which absorbs radiation or prevents the transmission of radiation to the wearer
  9. 15. The smallest particle of an element
  10. 19. The number of waves passing a given point per given unit of time
  11. 22. Exposure refers to two different occurrences, Exposure Rate and Exposure Time
  12. 24. effect Occur by chance and my occur without a threshold level of dose. Late term effects.
  13. 25. Negative charge in the atom
  14. 28. The distance between two successive crests or troughs
  15. 29. Emission The process of heat supplied to the cathode resulting in electrons energized off the cathode filament
Down
  1. 1. decay Process when an atom spontaneously emits particles and energy due to being unstable
  2. 3. No charge in the atom
  3. 4. equivalent Measured by the dosimeter worn by personnel exposed to radiographs (Sievert "Sy")
  4. 5. Any substance that has mass and takes up space
  5. 6. A positively charged electrode within the X-ray tube

  8. 16. Two filaments that are large and small are made of this metal
  9. 17. Spectrum Two types of energy used in X-ray are Electrical energy and electromagnetism
  10. 18. Heel Effect Has a greater intensity on the side of the cathode and diminishing toward the anode side
  11. 20. 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
  12. 21. radiation Dose measured by the service personnel calibrating the X-ray unit (air kerma "Gya)
  13. 23. The unit used to measure tube current (mA)
  14. 26. effect Noticeable short term effects due to, rarely, from diagnostic imaging setting
