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.

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






19. 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)

30. What type of bone tumors started elsewhere and spread to the location it was found






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






32. Film with: high detail - minimal graininess - increased exposure






33. To double the density






34. Can cause damage to living cells through the process of excitation or ionization of electrons in the orbits around atoms
