  10. MA
    number of xrays ultimately being produced due to the heating filament
  11. Kilovoltage peak kVp
    speeding up of electrons
  12. Penetration
    xrays that have gone through the object and interacted w. the film
  13. Absorption
    xrays that do no not pass through object and do not interact w/ film
  14. Radiograph
    visible photographic record on film produced due to the passage of erays through an object or body
