Introduction to Radiation Protection
Chapter 1 Questions and Answers Latest
Version Graded A+
What should you do if a personal dosimeter shows an unexpected high reading?
✔✔Report it immediately and seek medical evaluation if necessary.
What is one way to reduce radiation exposure for workers in a radiology department?
✔✔By rotating work shifts to limit the amount of time each worker spends near radiation
sources.
What is the main difference between alpha and beta radiation?
✔✔Alpha particles are large and highly charged, while beta particles are smaller and can
penetrate the skin more deeply.
Why is it important to keep radiation sources well-secured when not in use?
✔✔To prevent unauthorized access and minimize the risk of accidental exposure.
What does the term "radiation contamination" refer to?
1
,✔✔The presence of radioactive materials on surfaces, clothing, or people that can spread and
cause exposure.
How can you protect yourself from radiation exposure when working with X-rays?
✔✔By wearing protective lead aprons and standing behind shielding during procedures.
What is the most common source of background radiation?
✔✔Cosmic radiation from the sun.
What is the recommended distance to stay away from a radiation source whenever possible?
✔✔As far as possible to reduce exposure, following the inverse square law.
How do radiation safety signs help prevent exposure?
✔✔They provide warnings of potential hazards, reminding individuals to take necessary
precautions.
What is one of the primary reasons to monitor radiation levels in a workplace?
✔✔To ensure that exposure stays within safe limits for workers and the public.
2
, What is the concept of "controlled area" in radiation safety?
✔✔An area where radiation exposure levels are carefully monitored and restricted to minimize
risk.
What type of radiation is most commonly encountered in medical imaging?
✔✔X-rays and gamma rays.
Which organization is responsible for setting radiation safety standards in the United States?
✔✔The National Council on Radiation Protection and Measurements (NCRP).
Why is proper shielding important in radiation protection?
✔✔It reduces the intensity of radiation, protecting individuals from unnecessary exposure.
What does the term "radiation dose" refer to?
✔✔The amount of radiation absorbed by an individual or object.
What is the recommended action if a radiation spill occurs in a controlled area?
