What is the recommended annual whole-body effective dose limit for occupationally exposed individuals according to NCRP?

• A. 20 mSv
• B. 30 mSv
• C. 50 mSv
• D. 70 mSv

Answer: (C)

The recommended annual whole-body effective dose limit for occupationally exposed individuals according to the National Council on Radiation Protection and Measurements (NCRP) is set at 50 mSv. This dose limit is established to help ensure that workers in radiation-related fields remain within safe exposure levels, minimizing the risk of radiation-induced effects over time. The NCRP bases these limits on extensive research into the health effects of radiation exposure, ensuring they are protective for workers while allowing them to perform their duties effectively.

This limit takes into account the cumulative effects of radiation exposure and recognizes that higher doses can increase the likelihood of long-term health issues, including cancer. By adhering to this standard, occupational health and safety regulations strive to balance the benefits of radiation use in various industries, such as medical imaging and nuclear power, with the need to protect workers from excessive exposure.
