1. Which of the following changes in (KVP) will result in the greatest
reduction of patient dose, when (MAS) is adjusted to compensate for the
change? - Correct Answer-Increase kVp by 30%
2. Which of the following (IR) system speeds will result in the lowest patient
dose? - Correct Answer-Faster speed IR system
3. What is the primary purpose of using gonad shields during radiography?
- Correct Answer-Reduce the likelihood of genetic effects
4. Contact & shadow are two types of gonad shield - Correct Answer-
TRUE
5. When should gonad shields be used? - Correct Answer-When the
gonads are within 5cm of the radiation field

6. The greatest cause of unnecessary radiation to patients that can be
controlled by the limited operator are: - Correct Answer-repeat
exposures
7. The limited operator can reduce repeat exposures by: - Correct Answer-
clearly instructing patients
8. How does x-ray beam restriction minimize patient exposure - Correct
Answer-It limits the radiation field to the area of interest
9. What is the device that allows the limited operator to vary the size of the
radiation field - Correct Answer-Collimator
10. How does filtration reduce patient exposure - Correct Answer-
Removes longer wavelength photons
11. What is the National Council on Radiation Protection and
Measurements (NCRP) recommendation for the amount of total filtration
- Correct Answer-2.5mm Al Equivalent
12. What are the three principal methods used to protect limited
operators from unnecessary radiation exposure? - Correct Answer-1.

13. 2. Distance
14. 3. Shielding
15. Which of the following is NOT a type of personnel radiation shielding?
- Correct Answer-a. Apron
16. b. Glove
17. c. Thyroid shield
18. d. Shadow******** CORRECT
19. Personnel shielding must be worn on the rare occasion during which
the limited operator may need to remain in the radiographic room during
an exposure to assist the patient in maintaining the proper position.
What is the source of the greatest radiation hazard under this
circumstance? - Correct Answer-Scattered radiation from the patient
20. What is the term from radiation that escapes from the x-ray tube
housing? - Correct Answer-leakage radiation
21. Why are limited operators prohibited from activities that result in
direct exposure to the primary x-ray beam? - Correct Answer-They are
considered occupationally exposed individuals
22. Distance, as a method used to limit operator exposure, means that: -
Correct Answer-the operator should maximize the distance from the
source during an exposure.

23. Shielding worn for personnel protection is designed to attenuate what
source of exposure - Correct Answer-scatter radiation
24. Which of the following is an acronym for a common type of personnel
dosimeter - Correct Answer-TLD
25. What is the recommended placement for a personnel dosimeter on
the body of the limited operator - Correct Answer-The badge should be
worn in the region of the collar on the anterior surface of the body and
outside the lead apron if worn.
26. What is the NCRP recommended annual effective dose limit for
occupational exposure - Correct Answer-5.0 rem (0.05 severt)
27. What is the NCRP recommended monthly effective (or equivalent)
dose limit to the fetus for a prego worker? - Correct Answer-0.05 rem
(0.0005 Sv)
28. Radiation monitoring of personnel is required when what percentage
of the annual occupational effective dose limit is likely to be received -
Correct Answer-10%
