SECTION 1: INTRODUCTION TO RADIATION PROTECTION (Questions
1-25)
Question 1
Consequences of ionization in human cells include which of the following?
1. Creation of unstable atoms
2. Production of free electrons
3. Creation of highly reactive 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
A. 1, 2, and 3 only
B. 2, 3, and 4 only
C. 3, 4, and 5 only
D. 1, 2, 3, 4, and 5
Answer: D. 1, 2, 3, 4, and 5
Rationale: Ionization in human cells triggers a cascade of events. It creates
unstable atoms and produces free electrons. These free electrons can create highly
reactive free radicals (such as hydroxyl radicals from water radiolysis), which can
produce substances poisonous to the cell. This process can also create new biologic

molecules detrimental to the living cell, ultimately resulting in cellular injury that
may manifest as abnormal function or loss of function. All five consequences are
direct results of radiation-induced ionization .
Clinical Pearl: Understanding these cellular consequences forms the foundation
for why radiation protection is essential in medical imaging.
Question 2
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?
A. Ionizing radiation
B. Nonionizing radiation
C. Subatomic radiation
D. Ultrasonic radiation
Answer: A. Ionizing radiation
Rationale: Ionizing radiation is defined as radiation that has sufficient energy to
remove orbital electrons from atoms, creating ions (electrically charged particles).
This process is the fundamental mechanism by which radiation causes biological
damage. Nonionizing radiation (e.g., visible light, microwaves, radio waves) lacks
sufficient energy to cause ionization. Ultrasonic radiation uses sound waves and is
not a form of electromagnetic radiation .
Clinical Pearl: X-rays and gamma rays are the primary forms of ionizing radiation
encountered in medical imaging.
Question 3
Regarding exposure to ionizing radiation, patients who are educated to understand
the medical benefit of an imaging procedure are more likely to:
