Which regulatory body's guidelines are often followed for radiation safety?

The Nuclear Regulatory Commission (NRC) is the primary regulatory body in the United States responsible for overseeing the use of nuclear energy and materials, including guidelines for radiation safety. The NRC's mission encompasses protecting public health and safety, promoting the common defense and security, and protecting the environment. It establishes regulations and standards that govern the use of radioactive materials in various contexts, such as medical applications, industrial uses, and waste management.

The NRC develops guidelines that specify acceptable radiation exposure limits, required safety measures, and monitoring practices to ensure the safety of workers, the public, and the environment. These guidelines are crucial for organizations that handle radioactive materials, as they help in maintaining compliance with federal laws and minimizing radiation hazards.

In contrast, while the FDA, CDC, and NIH play important roles in public health and safety, their focus areas are distinct. The FDA regulates food, drugs, and medical devices; the CDC focuses on disease prevention and health promotion; and the NIH is involved in medical research. While they may incorporate elements of radiation safety in their work, particularly in medical contexts, the NRC is specifically dedicated to the regulatory oversight of radiation safety measures.
