Which organization sets radiation safety standards in the United States?

The organization that sets radiation safety standards in the United States is the Nuclear Regulatory Commission (NRC). The NRC is tasked with regulating the nation's civilian use of nuclear materials and ensuring that the public is protected from unnecessary exposure to radiation. Its role includes establishing safety standards for the use of nuclear energy and radioactive materials, which is critical for both public safety and environmental protection.

The FDA, while it oversees certain aspects of radiation safety, particularly in medical devices and the use of radioactive drugs, does not set overall radiation safety standards. The EPA is responsible for environmental protection and may deal with radiation in that context, but it is not the primary authority for safety standards regarding nuclear materials. The CDC focuses on public health and disease prevention, and while it may address health impacts from radiation exposure, it does not set the regulations governing radiation safety practices.
