1. What is the primary purpose of the ALARA principle in
medical radiation?
• A) To maximize image quality regardless of dose
• B) To keep radiation doses As Low As Reasonably
Achievable
• C) To eliminate all radiation exposure
• D) To standardize exposure factors across all patients
Answer: B) To keep radiation doses As Low As Reasonably
Achievable
Rationale: ALARA (As Low As Reasonably Achievable) is a
fundamental principle of radiation protection that guides MRTs to
1
,minimize patient and staff radiation exposure while maintaining
diagnostic image quality. This principle is central to Canadian
radiation safety standards and is a core competency on the
CAMRT exam .
2. Acute radiation syndrome typically occurs with:
• A) Small, repeated doses over many years
• B) A large dose (100 R or more) to the whole body
• C) Exposure to diagnostic imaging levels
• D) Any occupational exposure
Answer: B) A large dose (100 R or more) to the whole body
Rationale: Acute (early) radiation syndrome occurs when a large
dose of radiation is delivered to the whole body in a short
period. This is distinct from the long-term effects of radiation,
which develop over many years .
3. Long-term radiation effects typically occur:
2
, • A) Immediately after exposure
• B) Within 24 hours
• C) Years later (25-30 years)
• D) Only in patients with pre-existing conditions
Answer: C) Years later (25-30 years)
Rationale: Long-term radiation effects develop over many years,
typically 25-30 years after exposure. These effects fall into two
categories: genetic effects (passed to offspring) and somatic
effects (affecting the exposed individual) .
4. Which of the following is NOT a primary method of radiation
protection?
• A) Time
• B) Distance
• C) Shielding
• D) Collimation
Answer: D) Collimation
3
, Rationale: The three primary methods of radiation protection are
Time (minimizing exposure duration), Distance (maximizing
distance from the source), and Shielding (using protective
barriers). Collimation is a technique to reduce patient dose by
restricting the X-ray beam to the area of interest, but it is not one
of the three primary protection methods .
5. Which type of radiation effect involves changes that are
passed to future generations?
• A) Somatic effects
• B) Genetic effects
• C) Acute effects
• D) Stochastic effects
Answer: B) Genetic effects
Rationale: Genetic effects are changes in genetic material that
can be passed on to future generations. Somatic effects affect
