INTRODUCTION
This examination evaluates the knowledge and applied skills required of a Nuclear Facility
Safety Technician working in regulated nuclear environments. It assesses understanding of
radiation protection principles, operational safety procedures, contamination control,
emergency response actions, and compliance with federal nuclear regulatory standards.
,Candidates are tested using multiple-choice and scenario-based questions designed to
reflect real-world facility conditions. The exam emphasizes decision-making under safety-
critical conditions, technical interpretation of radiation data, and adherence to strict
occupational health standards required in nuclear facility operations and monitoring roles.
SECTION ONE (QUESTIONS 1–50)
Question 1
What is the primary principle used to minimize radiation exposure in nuclear facilities?
A. Time, Distance, Shielding
B. Containment, Ventilation, Filtration
C. Rotation, Isolation, Elimination
D. Dilution, Absorption, Reflection
🟢 Correct Answer: A. Time, Distance, Shielding
🔴 Explanation: ALARA principles reduce exposure by minimizing time near sources,
maximizing distance, and using shielding materials.
,Question 2
Which device is commonly used to measure cumulative radiation exposure?
A. Geiger counter
B. Thermometer
C. Dosimeter badge
D. Barometer
🟢 Correct Answer: C. Dosimeter badge
🔴 Explanation: Dosimeter badges track accumulated radiation dose over time for
personnel monitoring.
Question 3
What is ALARA an acronym for?
A. As Low As Reasonably Achievable
B. Always Limit Radiation Activity
C. Authorized Level of Radioactive Absorption
D. Absolute Limit of Radiation Allowance
🟢 Correct Answer: A. As Low As Reasonably Achievable
🔴 Explanation: ALARA is a radiation safety principle aiming to minimize exposure.
, Question 4
Which type of radiation is most effectively stopped by a sheet of paper?
A. Gamma
B. Alpha
C. Beta
D. Neutron
🟢 Correct Answer: B. Alpha
🔴 Explanation: Alpha particles have low penetration and are stopped by paper or skin.
Question 5
What is the primary purpose of containment systems in nuclear facilities?
A. Increase reactor efficiency
B. Store nuclear fuel
C. Prevent release of radioactive material
D. Cool turbine systems
🟢 Correct Answer: C. Prevent release of radioactive material
🔴 Explanation: Containment systems act as barriers to prevent environmental
contamination.
