What is the purpose of secondary barriers?

Protect from the useful primary beam
Protect from scattered and leakage radiation
Limit patient exposure during procedures
Enhance image resolution

The correct answer is: Protect from scattered and leakage radiation

The purpose of secondary barriers is to protect individuals from scattered and leakage radiation. In a radiography environment, the primary beam is directed towards the patient for diagnostic imaging, and secondary barriers are crucial in areas where personnel may be positioned during procedures. The secondary barriers are designed to attenuate the radiation that results from scattering off the patient's body and any leakage radiation that may escape from the x-ray tube. This is vital for maintaining safety standards in radiology departments, ensuring that staff and visitors are adequately protected from radiation exposure that may occur due to indirect sources. Effective design and placement of secondary barriers—commonly constructed of lead or other dense materials—are essential to reduce radiation exposure risks in areas adjacent to the examination room, contributing to overall safety protocols in radiographic practice.
