1. The milisievert (mSv) is equal to: 1/1000 of a sievert
2. Regarding exposure to ionizing radiation patients who are educated to un-
derstand the medical benefit of an imaging procedure are more likely to: suppress
any radiation phobia and be willing to assume a small chance of possible biologic damage.
3. Which of the following is a form of radiation that is capable of creating
electrically charged particles by removing orbital electrons from the atom of
normal matter through which it passes?: Ionizing radiation
4. if a patient asks a radiographer a question about how much radiation he or
she will receive from a specific x ray procedure, the radiographer can: respond by
using an estimation based on the comparison of radiation received from the x-ray to natural background radiation
received
5. The advantages of the BERT method are:
1. it does not imply radiation risk; it is simply a means for comparison.
2. it emphasizes that radiation is an innate part of our environment.
3. the answer given in terms of BERT is easy for the patient to comprehend.: al
of the options
6. Why should the selection of technical exposure factors for all medical imaging
procedures always follow ALARA?: Because radiation induced cancer does not appear to have a fixed
threshold.
7. The cardinal principles of radiation protection include which of the following
1) time
2)distance
3)shielding
4) all of these: all of these
8. In a hospital setting, which of the following professionals is expressly charged
by the hospital administration with being responsible for the execution, en-
forcement, and maintenance of the ALARA program?: Radiation Safety Officer
9. What unit is used to measure radiation exposure in the metric international
system of units?: Coulomb per kilogram
10. Which of the following provides the basis for determining whether an imag-
ing procedure of practice is justified?: Diagnostic efficacy
11. Which of the following is a method of explaining radiation to the public?: BERT

12. Which of the following radiation quantities is intended to be the best overall
measure of the biologic effects of ionizing radiation?: Effective dose
13. The term ALARA is synonymous with the term: optimization for radiation protection (ORP)
14. Electromagnetic radiation travels or propagates through space in the form
of a wave but can interact with matter as a particle of energy called a photon.
This dual nature is referred to as: Wave particle duality
15. Cosmic radiation occurs in which two forms?: Solar and galactic
16. Terrestrial radiation includes which of the following sources?: Long lived radioactive
elements such as uranium-238, radon-226, and thorium-232 that are present in variable quantities in the crust of the
earth
17. radiology departments or individuals radiologic technologists can "pledge"
to image gently. the pledge includes which of the following
1.) make the image gently message a priority in staff communication each year
2.) review the protocol recommendation and, when necessary, implement ad-
justments
3.) communicate openly with parents
4.) all of the options: all of the options
18. When exposed to high radon level in the home, which of the following groups
of people can have the highest risk of developing cancer?: Smokers
19. Which of the following helps shield the global population from exposure to
essentially all high-energy, bombarding cosmic rays?: Atmosphere and magnetic field of the
earth
20. -Through which of the following routes can radon enter houses?
1) crawl spaces under the living areas.
2) floor drains and sump pumps.
3) porous cement block foundations
4) all of the above: all of the above
21. Which of the following statements concerning the 1979 nuclear reactor
accident at TMI-2 is not true?: Many excess cancer deaths have been predicted to occur in the 2 million
people living within 50 miles of the plant at the time of the accident
22. What is the maximum period of time that a TDL may be worn as a personnel
device?: 3 months
