What does "controlled access" refer to in radiation safety?

"Controlled access" in radiation safety refers to the practice of limiting entry to specific areas where radiation exposure may exceed established safety limits. This is important to ensure that only authorized and trained personnel can enter those zones, thereby minimizing the risk of unnecessary exposure to harmful radiation. By restricting access, it helps maintain a safe environment for both workers and the general public.

This practice involves implementing signs, barriers, and access control measures to clearly delineate areas of concern. It also ensures that only individuals who have been adequately trained and are equipped with appropriate personal protective equipment can enter these potentially hazardous locations, thus prioritizing safety and minimizing risk.
