Test your basic knowledge |

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.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The shorter the wavelength of the x-ray - the more powerful the x-ray is

7. When.....collide with the anode - 99% of energy is released in the form of heat - and 1% of energy is in the form of x-rays






8. This is caused by mutations in gonadal cells - not seen until offspring are produced - mutations are not always bad






9. They don't move - they're found in dental units and portable units - cannot withstand the heat produced from large units

17. Is responsible for the number or quantity of x-rays






18. A type of electromagnetic radiation which have a shorter wavelength than visible light






19. Is the electrical current that heats the filament






20. When a body part is greater than or equal to.....you should use a grid






21. When more electrons hit the focal spot on the anode






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






23. Extra pain is also called






24. We should always try and stay How many feet from our x-ray machine






25. Screens are classified according to






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






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






28. The picture formed after the film has been exposed to x-rays and then processed into a visible image.






29. If there's bone in the way of an x-ray -. those parts would be






30. Areas on film that should be black but come out grey - due to storage






31. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






32. What is the term for an unknown cause






33. With the heel effect - more x-rays tend to be in the beam toward this end of the tube






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






35. Is the source of electrons






36. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






37. If the kVp is too high






38. The electrical current sent through the filament to cause this electron release is called






39. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






40. Tilting of the tube or grid is one reason for






41. This number in santes' rule refers to the distance the x-ray tube is from the x-ray film






42. Less forgiving - high contrast - cannot tolerate changes in exposure or processing






43. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






44. If there's no object in the way of an x-ray - the picture would be

46. Incorrect grid focus is one reason for






47. Amount of radiation a person can recieve in a calendar year






48. Film with: ultra speed - grainier image - less exposure needed






49. Hairloss or baldness






50. When this is exposed to x-rays - it will absorb photons (quanta) and give off photons of visible light which the film is sensitive to (give off blue light)
