Name of Participant:

1. Digital Imaging should result in lower dose to patients due to fewer retakes.

   True

   False

2. Exams should use techniques that are adjusted to administer the lowest radiation dose that yields image quality adequate for diagnosis or intervention. This is referred to as the ALARA Principle or "As Low As Reasonably Achievable"

   True

   False

3. A documented QA program is NOT necessary to comply with the Bureau of Radiation Protection regulations.

   True

   False

4. Bureau of Radiation Protection Registrants shall maintain records of surveys, calibrations, maintenance, and modifications including name of person performing service. Records shall be kept for inspection for a minimum of:

   9 months

   1 year

   3 years

   5 years

5. Imaging procedure should do more good than harm; therefore exams should be performed only when necessary to:

   Answer a medical question

   Determine disease process

   Guide a procedure

   All of the above

6. Medical X-rays are characterized by quantity and quality. Quantity is the number of X-rays reaching the patient. Factors that affect the quantity of x-rays produced are:

   Filtration

   mAs

   kVp

   All of the above

7. The Pennsylvania Bureau of Radiation Protection Regulations can be found in Pa Code, Title 25 Environmental Chapters 215-240. Federal regulations are incorporated into some Pennsylvania regulations by reference from Title 10 (or more commonly: 10 CFR)

   True

   False

8. The basic component of the x-ray tube that consists of a heated wire that produces a large source of electrons and a focusing cup used to direct them is known as the:

   Anode

   Tube housing

   Envelope

   Cathode

9. The measure of biological damage to the human caused by various types of ionizing radiation is known as:

   Equivalent dose

   Absorbed dose

   Exposure

   None of the above

10. Which statement is NOT correct?

    Primary beam should be sized to cover area of interest but not overly exceed it

    Generally lowest dose is achieved when kVp settings are decreased and mAs settings increased within the limits of obtaining a good image

    Historically, children have been imaged with settings similar to adults—resulting in unnecessary dose

    Workers should increase distance from patient, especially from beam side

11. The largest source of scatter produced during an exposure is due to the:

    Leakage radiation

    Useful beam

    Primary beam

    Patient

12. Quality is the penetrability or ability of an X-ray to pass through tissue. High quality X-rays increase the dose to the patient due to their ability to penetrate.
    
    

    True

    False

13. X-rays CANNOT make a person radioactive and CANNOT result in contamination (loose radioactive materials).

    True

    False

14. The regulatory annual effective whole body dose equivalent limit for a diagnostic X-ray worker is:

    3 rem

    5 rem

    7 rem

    15 rem

15. An example of particulate radiation is:

    Gamma

    Radio

    X-rays

    Beta

16. The part of the x-ray machine that removes unwanted low energy x-rays is known as the:

    Transformer

    Rectifier

    Filtration

    Collimator

17. Radiation exposure to the general public comes from a number of sources: What percentage of this exposure is due to background radiation?

    25%

    30%

    50%

    70%

18. Medical exposure to radiation has increased significantly, primarily due to:

    Better insurance coverage

    Increase in the number of elderly patients

    Increase in the number of CT exams performed

    Better access to medical care

19. Acute Effects (also referred to as early effects or deterministic effects) typically occur at high doses and appear within days to weeks of exposure. All of the following are examples of actue effects EXCEPT:

    Cancer

    Skin burns

    Sterility

    Loss of hair

20. To a close approximation 1R = 0.01 Gy to air.

    True

    False
