Which of the following is true about the secondary protective barrier?

The secondary protective barrier is designed specifically to safeguard against stray radiation, which includes scatter radiation produced when primary radiation interacts with various materials. This type of barrier is essential in environments where radiographic procedures occur, ensuring that individuals not directly involved with the procedure are protected from exposure to radiation that may have deviated from its intended path.

Stray radiation can occur in various forms, such as scatter and leakage radiation, making the role of the secondary protective barrier critical in maintaining safety standards. It is typically positioned around areas where radiation exposure is possible, but not directly against the primary source of radiation.

The nature of secondary barriers is such that they are not meant to withstand direct radiation hits, as is the case with primary barriers, which are specifically designed to absorb the direct radiation emitted from the source. Additionally, secondary barriers are not necessarily thicker than primary barriers nor limited to areas of high traffic. Their thickness and design depend on regulatory standards and the expected radiation levels, rather than strictly on traffic considerations.
