Which organization regulates the safe use of radiation in the United States?

The Nuclear Regulatory Commission (NRC) is the correct organization that regulates the safe use of radiation in the United States. The NRC's primary role is to oversee the licensing and regulation of commercial nuclear power plants, nuclear materials, and the safe use of radioactive materials. This includes ensuring that radiation exposure to the public and the environment is minimized and that facilities comply with established safety guidelines.

In addition to licensing, the NRC also sets standards for radiation protection, conducts inspections, and enforces compliance with safety regulations. This regulatory framework is crucial for maintaining safety in medical environments, nuclear power generation, and other uses of ionizing radiation.

Other organizations mentioned, such as the Food and Drug Administration (FDA), play a role in overseeing the safety of medical equipment and imaging technology that may utilize radiation, but they do not regulate radiation use directly. The Environmental Protection Agency (EPA) focuses on environmental health and pollution control, while the Centers for Disease Control and Prevention (CDC) is primarily concerned with public health, disease prevention, and health promotion. While each of these organizations has its own vital functions, the NRC specifically addresses the regulation and safety of radiation usage across various sectors.
