Radiation Protection Questions and
Answers Latest Version (2024/2025)
Already Passed
What is the first step in responding to a radiation emergency?
✔✔Assess the situation to determine the level of radiation and ensure safety procedures are
followed.
Why are regular medical check-ups important for radiation workers?
✔✔They help detect any early signs of radiation-related health issues, ensuring prompt
intervention.
How can radiation exposure be reduced when working with X-ray machines?
✔✔By using lead shielding, increasing distance from the source, and minimizing exposure time.
What is the role of the Radiation Safety Officer (RSO) in a workplace?
✔✔The RSO ensures that radiation safety protocols are followed and monitors radiation
exposure levels.

,How does ionizing radiation differ from non-ionizing radiation?
✔✔Ionizing radiation has enough energy to remove electrons from atoms, potentially causing
biological damage, while non-ionizing radiation lacks this ability.
Why is it important to check your radiation monitoring equipment before use?
✔✔Ensuring the equipment is functioning correctly helps provide accurate readings and protects
against exposure.
What are the key principles of radiation protection for medical professionals?
✔✔Minimizing exposure, using shielding, and applying proper technique to reduce patient and
worker exposure.
What is the difference between external and internal radiation exposure?
✔✔External exposure comes from radiation sources outside the body, while internal exposure
results from radioactive materials inhaled, ingested, or injected into the body.
Why is lead an effective shielding material for gamma radiation?
✔✔Lead is dense and absorbs gamma radiation efficiently, reducing exposure to individuals
nearby.
2
, What is a key consideration when disposing of radioactive waste?
✔✔Ensuring that the waste is properly stored and disposed of in accordance with regulatory
guidelines to prevent contamination.
How can radiation exposure be minimized during a fluoroscopy procedure?
✔✔By using the lowest possible dose, keeping the exposure time short, and applying proper
shielding.
What is the primary danger of high-dose radiation exposure to the human body?
✔✔It can cause cellular damage, increase cancer risk, and harm tissues or organs.
Why are radiation safety protocols constantly updated in the industry?
✔✔To keep pace with technological advancements and ensure that new risks are addressed with
effective protective measures.
How does radiation exposure contribute to the risk of genetic mutations?
✔✔Ionizing radiation can alter DNA, which can be passed down to offspring, increasing the risk
of genetic disorders.
