Chapter 1 — Introduction to Radiation Protection
Multiple Choice Questions (21+)
1. The primary purpose of radiation protection is to:
A) Improve image contrast
B) Minimize radiation exposure to patients and personnel
C) Increase radiographic speed
D) Enhance spatial resolution
Rationale:
Radiation protection ensures the ALARA principle (As Low As Reasonably
Achievable) to reduce harmful effects while maintaining diagnostic quality.
2. ALARA stands for:
A) Always Limit All Radiation Amounts
B) As Low As Reasonably Achievable
C) All Levels Are Radiologically Acceptable
D) As Long As Radiation Applies
Rationale:
ALARA emphasizes minimizing dose without compromising diagnostic
information.
3. Ionizing radiation is capable of:
A) Increasing body temperature only
B) Removing electrons from atoms, creating ions
, C) Producing sound waves
D) Non-ionizing interactions only
Rationale:
Ionizing radiation carries enough energy to disrupt atomic structure,
potentially causing cellular damage.
4. The risk of radiation-induced effects is influenced by:
A) Dose
B) Rate of exposure
C) Tissue sensitivity
D) All of the above
Rationale:
Radiation risk depends on dose, exposure time, and radiosensitivity of tissues.
5. Which of the following is a deterministic effect?
A) Cancer
B) Genetic mutations
C) Skin erythema
D) Stochastic effects
Rationale:
Deterministic effects occur above a threshold dose and severity increases with
dose (e.g., burns, cataracts).
6. Stochastic effects of radiation include:
A) Hair loss
B) Cancer and genetic mutations
C) Skin redness
D) Sterility
Rationale:
Stochastic effects occur randomly, with probability increasing with dose, but
severity does not depend on dose.
7. Radiation protection principles include:
A) Time
