Radiation Protection (Exam 1) Ch - 1, 2,
3 & 4 Questions and Answers Latest
Version Graded A+
Which body organs are most sensitive to radiation?
✔✔ Bone marrow, reproductive organs, and the gastrointestinal tract.
How does shielding reduce radiation exposure?
✔✔ It blocks or absorbs radiation before it reaches the body.
What is the purpose of a film badge in radiation monitoring?
✔✔ To measure cumulative radiation exposure over time.
Why is it important to follow radiation protection guidelines?
✔✔ To prevent unnecessary exposure and reduce health risks.
What type of radiation protection is used in nuclear power plants?
✔✔ Thick concrete walls, lead shielding, and controlled exposure times.
1
,What is radiation sickness?
✔✔ A condition caused by excessive exposure to high doses of radiation, leading to symptoms
like nausea, fatigue, and burns.
How does a thyroid shield protect against radiation?
✔✔ It covers the thyroid gland, reducing exposure to scattered radiation.
What is the difference between ionizing and non-ionizing radiation?
✔✔ Ionizing radiation has enough energy to remove electrons from atoms, while non-ionizing
radiation does not.
What is the function of a radiation survey meter?
✔✔ To measure radiation levels in an area to ensure safety.
How does radiation affect DNA?
✔✔ It can cause mutations, potentially leading to cancer or genetic defects.
2
, What is the main purpose of medical radiation protection regulations?
✔✔ To protect patients and healthcare workers from unnecessary radiation exposure.
What are the three fundamental principles of radiation protection?
✔✔ Time, distance, and shielding.
How does reducing exposure time help in radiation protection?
✔✔ Less time near a radiation source results in a lower dose received.
Why is distance important in radiation safety?
✔✔ Increasing distance from a radiation source reduces exposure due to the inverse square law.
What material is most effective for shielding against X-rays and gamma radiation?
✔✔ Lead.
Which type of radiation can be stopped by a thin sheet of paper?
✔✔ Alpha radiation.
