Which organization is responsible for regulating mammography radiation standards?

The correct answer is the FDA (Food and Drug Administration). The FDA is responsible for establishing and enforcing standards for the quality and safety of mammography facilities in the United States. This includes setting regulatory requirements for equipment, personnel qualifications, and facility practices to ensure that mammography services are safe and effective.

The Mammography Quality Standards Act (MQSA) of 1992 gave the FDA the authority to regulate mammography, ensuring that women receive high-quality imaging and reducing the risks associated with radiation exposure. The FDA conducts inspections of mammography facilities to ensure compliance with these standards and also monitors the performance of mammography equipment and the qualifications of healthcare professionals performing the imaging.

Other organizations mentioned, such as the CDC (Centers for Disease Control and Prevention), primarily focus on public health and disease control rather than equipment regulation, while the NRC (Nuclear Regulatory Commission) regulates the use of radioactive materials, which is broader and not limited specifically to mammography. The WHO (World Health Organization) provides guidance on health topics on an international scale but does not regulate mammography standards directly.

Thus, the FDA's specific role in regulating mammography standards makes it the correct choice for this question.
