ARRT registry review covering Radiation Protection

QuestionAnswer
1. According to the National Council on Radiation Protection and Measurements (NCRP), the monthly gestational dose-equivalent limit for embryo/fetus of a pregnant radiographer is 0.5 mSv (Lange Q&A p. 125)
2. What percentage of public exposure to ionizing radiation is from medical sources? 50% (Lange Q&A p. 125)
3. The interaction between ionizing radiation and the target molecule that is most likely to occur is the indirect effect (Lange Q&A p. 126)
4. The unit used to express kinetic energy released in matter is the kerma (Lange Q&A p. 126)
5. Which acute radiation syndrome requires the largest exposure before the associated effects become apparent? Central nervous system (Lange Q&A p. 126)
6. What is the established annual occupational dose-equivalent limit for the lens of the eye? 150 mSv (Lange Q&A p. 126)
7. Occupational radiation monitoring is required when it is possible that the individual might receive more than one-tenth the annual dose limit (Lange Q&A p. 126)
8. Irradiation of water molecules within the body and their resulting breakdown is termed radiolysis (Lange Q&A p. 126)
9. The x-ray interaction with matter that is responsible for the majority of scattered radiation reaching the image receptor Compton scatter (Lange Q&A p. 127)
10. Each time a x-ray beam scatters, its intensity at 1 m from the scattering object is what fraction of its original intensity? 1/1,000 (Lange Q&A p. 127)
11. A thermoluminescent dosimetry system would use which of the following crystals lithium fluoride (Lange Q&A p. 127)
12. In radiation protection, the product of absorbed dose, tissue weighting factor, and radiation weighting factor is used to determine EfD (Lange Q&A p. 128)
13. The most radiosensitive portion of the GI tract is the small bowel (Lange Q&A p. 129)
14. What is the term used to describe x-ray photon interaction with matter and the transference of part of the photon's energy to matter? scattering (Lange Q&A p. 129)
15. Any wall that the useful x-ray beam can be directed toward is called a primary barrier (Lange Q&A p. 129)
16. What unit of measure is used to express ionizing radiation dose to biologic material? Rem (Sv) (Lange Q&A p. 130)
17. The skin response to radiation exposure that appears as hair loss is known as epilation (Lange Q&A p. 130)
18. The reduction in the intensity of an x-ray beam as it passes through material is termed attenuation (Lange Q&A p. 130)
19. What is used to illustrate the relationship between exposure to ionizing radiation and possible resultant biologic responses? dose-response curve (Lange Q&A p. 131)
20. For radiographic examinations of the skull, it is generally preferred that the skull be examined in the PA projection (Lange Q&A p. 132)
21. The amount of time that x-rays are being produced and directed toward a particular wall is referred to as the use factor (Lange Q&A p. 133)
22. the unit of measurement used to express occupational exposure is the rem (Sv) (Lange Q&A p. 134)
23. Which term is used to describe beam quality? HVL (Lange Q&A p. 134)
24. the automatic exposure device that is located immediately under the x-ray table is the ionization chamber (Lange Q&A p. 135)
25. Filters used in radiographic x-ray tubes generally are composed of aluminum (Lange Q&A p. 136)
