Questions and Answers Latest Version
Graded A+
What is the purpose of establishing radiation dose limits for workers?
✔✔Dose limits help protect workers from harmful radiation exposure and ensure that their
cumulative dose stays within safe levels.
What is the relationship between radiation dose and risk of cancer?
✔✔Higher radiation doses increase the risk of developing cancer, making dose reduction and
monitoring crucial for protection.
What should be done if a worker exceeds their radiation dose limit?
✔✔The worker should be evaluated by a medical professional, and corrective actions should be
taken to prevent further exposure.
How does radiation contamination differ from radiation exposure?
✔✔Contamination refers to the presence of radioactive materials on surfaces or in the
environment, while exposure refers to the body’s interaction with radiation.

,Why is it essential to wear gloves when handling radioactive materials?
✔✔Gloves protect the skin from direct contact with radioactive materials, preventing
contamination and reducing exposure.
What is the purpose of a radiation safety audit?
✔✔A radiation safety audit evaluates the effectiveness of safety measures, identifies potential
risks, and ensures compliance with regulations.
How does ventilation contribute to radiation protection?
✔✔Proper ventilation helps reduce the concentration of radioactive particles in the air,
minimizing inhalation risks for workers.
What does the term "radiation protection factor" refer to?
✔✔The radiation protection factor is a measure of the effectiveness of a protective barrier in
reducing radiation exposure.
How does radiation exposure affect the human body?
2
, ✔✔Radiation exposure can cause cellular damage, increase cancer risk, and lead to genetic
mutations.
Why is it important to follow the "ALARA" principle?
✔✔The ALARA principle (As Low As Reasonably Achievable) helps minimize radiation
exposure to safe levels.
What is the role of shielding in radiation protection?
✔✔Shielding absorbs or deflects radiation, reducing exposure to individuals in the area.
What is the significance of using personal protective equipment (PPE) in radiation
environments?
✔✔PPE serves as a physical barrier to reduce direct radiation exposure and prevent
contamination.
How do radiation surveys contribute to safety in a controlled area?
✔✔Radiation surveys help detect areas with high radiation levels and ensure that safety
protocols are being followed.
