1. The ALARA philosophy should - Correct Answer: 1. be a main part of every health
care facility's personnel radiation control program
be established and maintained because there are no established dose limits for the
amount of radiation that patients may receive for individual imaging procedures
show that radiographers and radiologist in a facility have considered reasonable actions
that will reduce patient and personnel dose below required limits
2. When an imaging procedure is justified in terms of medical necessity, a diagnostic
efficacy is achieved when optimal-quality images, revealing the presence of absence of
disease, are obtained with - Correct Answer: minimal radiation exposure to the
patient
3. For the welfare of patients and the workers, facilities providing imaging services must
have - Correct Answer: an effective radiation safety program
4. When radiation is safely and prudently used in imaging of patients, the benefit of the
exposure can be ________ and the potential risk of biologic damage is ______ -
Correct Answer: maximized; minimized
5. Which of the following cardinal principles of radiation protection can be applied to both
the patient and the radiographer - Correct Answer: 1. time
2. distance
3. shielding
,6. Which of the following recommend the use of background equivalent radiation time for
improving patient understanding and reducing fear and anxiety associated with having
an x-ray procedure - Correct Answer: National Council on Radiation Protection and
Measurements
7. BERT is a - Correct Answer: method of comparison
8. which of the following terms is an attempt to provide a quantity that is a measure of
general harm in humans - Correct Answer: effective dose
9. typically, people are more likely to accept a risk if they perceive that - Correct
Answer: the potential benefit to be obtained is greater than the risk involved
10. the most effective tool for diagnosing breast cancer continues to be - Correct
Answer: high quality mammography
11. the millisievert a subunit of the sievert is equal to - Correct Answer: 1/1000 of a Sv
12. repetition of a radiographic exposure because of poor patient positioning results in -
Correct Answer: an increase in total radiation exposure to the patient and the
radiographer
13. target (anode) - Correct Answer: Is the positive side of the x-ray tube and is involved
in x-ray production
14. Glass envelope - Correct Answer: a glass vacuum tube that contains the anode and
cathode of the x-ray tube
,15. how can humans safely control the use of radiant energy - Correct Answer: by using
the knowledge of radiation induced hazards gained over many years and by employing
effective methods to limit or eliminate those hazards
16. how can radiologic technologists reduce radiation exposure to patients and to
themselves - Correct Answer: by using protective devices correctly, following
established procedures and by using correct x-ray settings that reduce exposures
17. as ionizing radiation passes through matter, what is the event that may cause injury in
normal biologic tissue - Correct Answer: while passing through matter, ionizing
radiation can produce positively and negatively charged ion during its path. These
charged ions and the electrons ejected along the way, all may cause damage to the
normal biologic tissue
18. How can imaging personnel apply the three cardinal principles of radiation protection to
minimize occupational exposure? - Correct Answer: reducing time spent in the room
with x-ray produced, stand at the greatest distance possible from an energized x-ray
beam and interpose a radiation absorbent shielding material between the radiographer
and the source of radiation
19. what principles can be used as a method for comparing the amount of radiation in
various health care facilities in a particular area for specific imaging procedures -
Correct Answer: the ALARA principle can be used as a method for comparing the
amount of radiation used in various health care facilities in a particular area for specific
imaging procedures
20. what is the goal for modern radiation protection programs - Correct Answer: the
goal for modern protection programs are to protect persons from both short and long
term effects of radiation
, 21. regarding ALARA program in a hospital setting, what are three responsibilities for the
program that are entrusted to the radiation safety officer by the administration -
Correct Answer: the RSO is expressly charged by the administration to be directly
responsible for the execution, enforcement, and maintenance of the ALARA program
22. how is risk weighted against benefit in medical radiology - Correct Answer: when
being used for the welfare of others, ionizing radiation must far out weigh any chance of
inducing radiogenic malignancy or any genetic effects
23. list 4 good practices that apply to radiologic technologists and radiologists - Correct
Answer: educated in safe operation of x-ray producing, use protective devices correctly,
follow established procedures, and selecting x-ray setting to reduce exposure
24. on what reference values for patient dose based on - Correct Answer: large scale
surveys of actual measurements of x-ray machines in hospitals
25. what are adverse biologic effect - Correct Answer: damage to living tissue of animals
and humans exposed to ionizing radiation
26. how fast do x-rays travel in a straight line until they interact with atoms - Correct
Answer: at the speed of light
27. define the term radiation protection - Correct Answer: protective measures
employed by radiation workers to safeguard patients, personnel and the public from
unnecessary exposures
28. who should justify the need for every radiation procedure and accept basic responsibility
for protecting the patient from nonuseful radiation exposure - Correct Answer: the
physician
