CAMRT Radiography Practice Exam

What is the NCRP recommended annual occupational dose limit?

1. 25 mSv

2. 50 mSv

3. 75 mSv

4. 100 mSv

The correct answer is: 50 mSv

The National Council on Radiation Protection and Measurements (NCRP) has set forth guidelines to ensure the safety of individuals who are occupationally exposed to ionizing radiation. The recommended annual occupational dose limit is established to minimize the risk of stochastic effects, such as cancer, while allowing for necessary exposure in medical and industrial settings. The appropriate annual occupational dose limit is set at 50 mSv. This level reflects a balance between sufficient protection for radiation workers and the operational demands of their professions, recognizing that they may be exposed to radiation levels higher than the general public. The limit is designed to safeguard against excessive exposure over time and takes into account the potential cumulative effects that could arise from continuous occupational exposure. Understanding this limit is crucial not only for compliance with safety regulations but also for fostering a culture of safety in professions that involve radiation exposure. It aligns with international safety standards, ensuring that radiographers and other health professionals operate within safe limits while performing their duties.
