What are the consequences of ionization in human cells? Answer: 1. Creation of
unstable atoms. 2. Production of free electrons. 3. Creation of highly reactive free
molecules (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 as abnormal function or loss of function. 6. Production of low-
energy x-ray photons.
What type of radiation is capable of creating electrically charged particles by
removing orbital electrons? Answer: Ionizing radiation.
How are patients likely to respond when educated about the medical benefits of an
imaging procedure involving ionizing radiation? Answer: They are more likely to
suppress any radiation phobia and be willing to assume a small chance of possible
biologic damage.
What is the equivalent of one millisievert (mSv) in terms of sieverts? Answer:
1/1000 of a sievert.
What are the advantages of the BERT method? Answer: 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.
How should a radiographer respond to a patient asking about the radiation they will
receive from an x-ray procedure? Answer: By using an estimation based on the
comparison of radiation received from the x-ray to natural background radiation.

and radiation safety aspects.
What is the focus of Chapter 15? Answer: Management of imaging personnel
radiation dose during diagnostic x-ray procedures.
What does Chapter 16 discuss? Answer: Radioisotopes and radiation protection.
What does it mean that radiation-induced cancer does not have a fixed threshold?
Answer: It means there is no dose level below which a person has no chance of
developing this disease.
What are the cardinal principles of radiation protection? Answer: Time, Distance,
Shielding.
Who is responsible for the execution, enforcement, and maintenance of the ALARA
program in a hospital? Answer: The Radiation Safety Officer.
Why is it difficult to answer questions about the amount of radiation a patient will
receive during an x-ray? Answer: Because the received dose is specified in
different units and is often not comprehensible to patients.
What type of radiation are X-rays classified as? Answer: Ionizing radiation.
What unit is used to measure radiation exposure in the metric International System
of Units? Answer: Coulomb per kilogram.
What organization was founded in 2007 to promote pediatric-specified scan
protocols? Answer: Alliance for Radiation Safety in Pediatric Imaging.
What provides the basis for determining whether an imaging procedure is justified?
Answer: Diagnostic efficacy.

, What method is used to explain radiation to the public? Answer: BERT
(Background Equivalent Radiation Time).
What does the pledge to 'image gently' include? Answer: Making the image gently
message a priority, reviewing protocol recommendations, and communicating openly
with parents.
In a team approach to patient care, what is emphasized? Answer: Responsibility for
areas of expertise and the importance of communication.
Which radiation quantity is considered the best overall measure of the biologic
effects of ionizing radiation? Answer: Effective dose.
What do people typically require to accept a risk? Answer: They perceive that the
potential benefit is greater than the risk involved.
What is true regarding safe dose levels for radiation-induced malignant disease?
Answer: It appears that no safe dose level exists.
What does the ALARA principle stand for? Answer: As Low As Reasonably
Achievable.
What is the primary purpose of the ALARA principle in healthcare? Answer: To
compare the amount of radiation used in various health care facilities for specific
imaging procedures.
Which organizations are primarily concerned with the ALARA principle? Answer:
Regulatory agencies.
What does diagnostic efficacy include? Answer: 1. Determining if an imaging
procedure is justified. 2. Producing optimal quality images with the least radiation
exposure. 3. Adhering to radiation safety guidelines. 4. Revealing the presence or
absence of disease.
Which of the following is required by The Joint Commission for CT? Answer: 1.
Annual education of staff in dose reduction techniques. 2. Minimum qualifications for
