MULTIPLE CHOICE

• Consequences of ionization in human cells include
• creation of unstable atoms.
• production of free electrons.
• creation of highly reactive free radicals capable of producing substances poisonous to the

cell.

• creation of new biologic molecules detrimental to the living cell.
• injury to the cell that may manifest itself as abnormal function or loss of function.
• 1, 2, and 3 only
• 2, 3, and 4 only
• 3, 4, and 5 only
• 1, 2, 3, 4, and 5

ANS: D

• 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
• Nonionizing radiation
• Subatomic radiation
• Ultrasonic radiation

ANS: A

• Regarding exposure to ionizing radiation, patients who are educated to understand the medical

benefit of an imaging procedure are more likely to

• assume a small chance of biologic damage but not suppress any radiation phobia

they may have.

• cancel their scheduled procedure because they are not willing to assume a small

chance of biologic damage.

• suppress any radiation phobia but not risk a small chance of possible biologic

damage.

• suppress any radiation phobia and be willing to assume a small chance of possible

biologic damage.

ANS: D

• The millisievert (mSv) is equal to
• 1/10 of a sievert.
• 1/100 of a sievert.
• 1/1000 of a sievert.
• 1/10,000 of a sievert.

ANS: C 1 / 4

• The advantages of the BERT method are
• it does not imply radiation risk; it is simply a means for comparison.
• it emphasizes that radiation is an innate part of our environment.
• it provides an answer that is easy for the patient to comprehend.
• 1 and 2 only
• 1 and 3 only
• 2 and 3 only
• 1, 2, and 3

ANS: D

• 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.

• avoid the patient’s question by changing the subject.
• tell the patient that it is unethical to discuss such concerns.
• refuse to answer the question and recommend that he or she speak with the

referring physician.

ANS: A

• Why should the selection of technical exposure factors for all medical imaging procedures

always follow ALARA?

• So that referring physicians ordering imaging procedures do not have to accept

responsibility for patient radiation safety.

• So that radiographers and radiologists do not have to accept responsibility for

patient radiation safety.

• Because radiation-induced cancer does not appear to have a dose level below

which individuals would have no chance of developing this disease.

• Because radiation-induced cancer does have a dose level at which individuals

would have a chance of developing this disease.

ANS: C

• The cardinal principles of radiation protection include which of the following?
• Time
• Distance
• Shielding
• 1 only
• 2 only
• 3 only
• 1, 2, and 3

ANS: D

• In a hospital setting, which of the following professionals is expressly charged by the hospital

administration with being directly responsible for the execution, enforcement, and maintenance of the ALARA program?

• Assistant administrator of the facility
• Chief of staff 2 / 4

• Radiation Safety Officer
• Student radiologic technologist

ANS: C

• Why is a question concerning the amount of radiation a patient will receive during a specific

x-ray procedure difficult to answer?

• Because the received dose is specified in a number of different units of measure
• Because the scientific units for radiation dose are normally not comprehensible by a patient
• Because the patient should not receive any information about radiation dose
• 1 and 2 only
• 1 and 3 only
• 2 and 3 only
• 1, 2, and 3

ANS: A

• X-rays are a form of which of the following kinds of radiation?

• Internal
• Nonionizing

ANS: B

• What unit is used to measure radiation exposure in the metric International System of Units?
• Coulomb per kilogram
• Milligray
• Millisievert
• Sievert

ANS: A

• What organization was founded in 2007 that continues their pursuit to raise awareness of the

need for dose reduction protocols by promoting pediatric-specified scan protocols to be used for both radiology and nonradiology users of CT?

• U.S. Food and Drug Administration
• Alliance for Radiation Safety in Pediatric Imaging.
• American Registry of Radiologic Technologists
• The Joint Commission

ANS: B

• Which of the following provides the basis for determining whether an imaging procedure or

practice is justified?

• ALARA concept
• BERT method
• Diagnostic efficacy
• NEXT program

ANS: C

• Which of the following is a method of explaining radiation to the public? 3 / 4

• ALARA
• BERT
• ORP
• NEXT

ANS: B

• Radiology departments or individual radiologic technologists can “pledge” to image gently.

The pledge includes which of the following?

• Make the image gently message a priority in staff communications each year.
• Review the protocol recommendations and, when necessary, implement adjustments to

practice processes.

• Communicate openly with parents.
• 1 only
• 2 only
• 3 only
• 1, 2, and 3

ANS: D

• In a team approach to patient care, various participants
• assume responsibility for their areas of expertise.
• emphasize the importance of communication throughout the team
• rotate as the person in charge of the team
• 1 and 2 only
• 1 and 3 only

• 1, 2, and 3

ANS: A

• Which of the following radiation quantities is intended to be the best overall measure of the

biologic effects of ionizing radiation?

• Exposure
• Effective dose
• Absorbed dose
• There is no radiation quantity that is intended to be the best overall measure of the

biologic effects of ionizing radiation.

ANS: B

• Typically, people are more willing to accept a risk if they perceive that the potential benefit to

be obtained is

• greater than the risk involved.
• equal to the risk involved.
• less than the risk involved.
