What is the definition of a controlled area in radiation safety?

A controlled area in radiation safety is defined as areas within the site boundary but outside restricted zones. These areas are designated to limit access based on the potential for radiation exposure, allowing only authorized personnel to enter. The presence of radiation sources in these areas necessitates specific safety measures to ensure the protection of individuals from potential exposure.

Unlike unrestricted areas, which allow public access, controlled areas have access restrictions to manage exposure risks effectively. While they may not be as strictly controlled as restricted zones, where access is highly limited due to higher radiation levels, controlled areas still require monitoring and adherence to safety protocols. Therefore, understanding this distinction is crucial for maintaining safety standards and ensuring the protection of both workers and the public.
