Which international and national organizations provide dose limits and risk guidelines for health physics?

• A. ICRP, NCRP, IAEA
• B. FDA, EPA, NIH
• C. WHO, UNICEF, UNESCO
• D. FIFA, IOC, PGA

Answer: (A)

Dose limits and risk guidelines in health physics come from organizations that set and harmonize radiation protection standards internationally and nationally. The International Commission on Radiological Protection (ICRP) issues internationally recommended dose limits and risk coefficients used around the world. The National Council on Radiation Protection and Measurements (NCRP) translates those recommendations into U.S. national guidance and protective practices. The International Atomic Energy Agency (IAEA) develops safety standards and guidance that adopt and implement ICRP principles across member states, assisting with regulatory programs and practical protection in medical, industrial, and nuclear settings.

Other groups listed aren’t the primary sources for these standards: the FDA, EPA, and NIH play related roles in specific areas but do not set universal dose limits; WHO, UNICEF, and UNESCO focus on broader health and development issues rather than radiological protection standards; and the remaining options are unrelated to radiation safety.
