Which organization provides recommended dose limits for radiation exposure?

• A. ICRP
• B. OSHA
• C. WHO
• D. NCRP

Answer: (D)

Understanding who sets recommended dose limits for radiation exposure helps you see where the numbers come from. The National Council on Radiation Protection and Measurements (NCRP) is the body that compiles research, performs risk assessment, and publishes official recommendations for occupational and public radiation dose limits. In practice, these NCRP recommendations guide national regulations and the safety programs at workplaces and institutions. The ICRP provides international guidance that informs these standards, but the explicit dose-limit figures used in many settings originate from NCRP in the U.S. OSHA enforces safety rules but does not itself issue the dose limits; WHO offers health guidance, not the numeric exposure limits. So, in this context, NCRP is the best answer.
