ANSWERS
The term as low as reasonably achievable (ALARA) is synonymous with the term -
Answers - Optimization for radiation protection (ORP)
Effective protective actions take into consideration
1. both human and environmental physical determinants.
2. technical elements.
3. procedural factors. - Answers - All three
The millisievert (mSv) is equal to - Answers - 1/1000 of a sievert
Which of the following provides the basis for determining whether an imaging procedure
or practice is justified? - Answers - Efficacy
Why is a question concerning the amount of radiation a patient will receive during a
specific x-ray procedure difficult to answer?
1. Because the received dose is specified in a number of different units of measure.
2. Because the scientific units for radiation dose are normally not comprehensible by a
patient.
3. Because the patient should not receive any information about radiation dose. -
Answers - 1 and 2 only
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 - Answers - respond by
using an estimation based on the comparison of radiation received from the x-ray to
natural background radiation received.
In a team approach to patient care, various participants
1. assume responsibility for their areas of expertise.
2. emphasize the importance of communication throughout the team.
3. rotate as the person in charge of the team. - Answers - 1 and 2 only
Regarding exposure to ionizing radiation, patients who are educated to understand the
medical benefit of an imaging procedure are more likely to - Answers - suppress any
radiation phobia and be willing to assume a small chance of possible biologic damage.
Radiology departments or individual radiologic technologists can "pledge" to image
gently. The pledge includes which of the following? - Answers - All of the options
Typically, people are more willing to accept a risk if they perceive that the potential
benefit to be obtained is - Answers - greater than the risk involved
, Consequences of ionization in human cells include
1. creation of unstable atoms.
2. production of free electrons.
3. creation of highly reactive free molecules (called free radicals) capable of producing
substances poisonous to the cell.
4. creation of new biologic molecules detrimental to the living cell.
5. injury to the cell that may manifest itself as abnormal function or loss of function.
6. production of low-energy x-ray photons. - Answers - 12346
The cardinal principles of radiation protection include which of the following? - Answers
- Time, distance, shielding
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? - Answers - Ionizing radiation
Which of the following statements below is true? - Answers - It appears that no safe
dose level exists for radiation-induced malignant disease.
The advantages of the BERT method are
1. BERT does not imply radiation risk; it is simply a means for comparison.
2. BERT emphasizes that radiation is an innate part of the environment.
3. BERT provides an answer that is easy for the patient to comprehend. - Answers - All

2. producing optimal quality images with the least radiation exposure to the patient.
3. adhering to radiation safety guidelines.4. revealing the presence or absence of
disease in a patient. - Answers - 1234
An effective radiation safety program requires a firm commitment to radiation safety by:
1. Patients
