Which organization routinely samples air, water, and food supplies for radionuclides?

The correct response indicates that all of the listed organizations—FDA, USEPA, and NRC—engage in the sampling of air, water, and food supplies for radionuclides.

The FDA (Food and Drug Administration) is responsible for ensuring the safety and security of the nation’s food supply and its regulation includes monitoring food products for contaminants, including radionuclides, particularly in food items that might be affected by nuclear incidents or contamination.

The USEPA (United States Environmental Protection Agency) plays a critical role in monitoring and regulating environmental pollutants, including radionuclides. The agency conducts various programs to sample and analyze environmental media—such as air and water—for contaminants to protect public health and the environment.

The NRC (Nuclear Regulatory Commission) specifically oversees the use of nuclear energy and materials. Part of its mission involves ensuring that radioactive materials are handled safely and that environmental monitoring occurs around nuclear facilities to protect public health. This can include sampling for radionuclides in air, water, and soil.

Since all three organizations have roles related to the sampling and monitoring of radionuclides across various environmental mediums, the answer reflects a comprehensive understanding of public health and environmental safety.
