Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.

7. These cells are the most sensitive to radiation






8. Hairloss or baldness






9. Legally - a non-pregnant woman is required to hold a HBC dog for radiographs in NYS






10. What type of films need a lot more x-ray exposure and more time to expose them






11. What type of film has no screens or film cassettes






12. MAs for extremities






13. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






14. Is on the anode and is angled at approximately 20 degrees from vertical






15. When doing a lateral radiograph of the thorax/chest - the x-ray beam should be centered over what specific anatomical landmark






16. Crystals + x-rays = ?






17. Most commonly used film - compromise between graininess and speed (detail)






18. A device that moves the grid back and forth under the table. it helps to prevent grid lines from showing






19. X-ray machines come with a set one - we cannot adjust it






20. The smaller the focal spot






21. Must change if the FFD changes






22. Is determined by the ratio of the height of the lead strips to the distance between them






23. What specific part of the eye is cloudy with a cataract






24. The tendency of a luminescent compound to continue to give off light after x-radiation has stopped






25. If there's far or muscle in the way of an x-ray - those parts would be






26. If the thorax is greater than or equal to....you should use a grid






27. These screens have increased definition/detail - need to have increased radiation exposure






28. Lead equivalent for apron






29. Is the electrical current that heats the filament

33. An abdominal radiograph should be taken at the peak of expiration






34. Dislocations or separations






35. When the density difference is great - there is






36. These screens are the most common type - they give good resolution with relatively low exposure

40. When processing film - the black areas are made of






41. Is only 1/3 the size of the actual focal spot






42. Outer layer of disk ( dries out and cracks and causes disk to herniate)






43. Extra pain is also called






44. This gives you the desired mAs - and it gives less time for your patient to move






45. Radiographic signs dont always agree with what






46. Safe Operating Procedures






47. Rotating anode






48. The effective focal spot is approximately 1/3 the size of the actual focal spot






49. Is the source of electrons






50. If the x-ray tube is not 36-40 inches from the grid - this is called the
