Unit 1: Introduction to Radiation Protection
Across
- 3. number that indicates organ and tissue radiosensitivity
- 5. interaction between x-ray photon and inner-shell electron
- 8. x-ray beam before after it exits the tube but before it enters the patient but
- 10. energy deposited per length of track
- 11. type of radiation that can cause biologic damage
- 13. radiation that comes from the earth
- 16. dose that accounts for the type of ionizing radiation received
- 21. transfer of energy from radiation to air
- 23. also known as classic, elastic, or unmodified scatter
- 25. acronym for as low as reasonably achievable
- 26. radiation induced effects that are seen in children of the exposed individual
- 27. SI unit for absorbed dose
- 28. scatter responsible for most of the scattered radiation in an radiographic exam
- 29. one of the most common sources of natural background radiation
- 31. radiation induced reactions that occur months or years after exposure
- 32. measure of general harm
- 33. method of comparing the amount of radiation recieved with an amount of background radiation
- 34. radiation that comes from the sun and other stars
Down
- 1. one of the three cardinal rules of radiation protection
- 2. not sperm or ova
- 4. random
- 6. type of cancer that was prevalent after the Chernobyl disaster
- 7. weighting factor that describes differences in types of radiation
- 9. SI unit for effective dose
- 12. amount of energy per mass that has been absorbed
- 14. sum of EfD equivalents from radiation exposure
- 15. the possibility of inducing adverse biological effects
- 17. the higher this number is, the more attenuation results
- 18. x-ray photons that have undergone absorption or scatter and do not reach the IR
- 19. photons type of radiation that strikes the IR producing the image
- 20. some of the first radiation induced deaths and injuries were a direct result of this type of exposure
- 22. effects of radiation that appear shortly after exposure
- 24. the degree of accuracy
- 30. measure of air kerma over the patient's surface
