  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
