What is one of the main sources of secondary radiation?

Secondary radiation primarily refers to the radiation that is generated as a result of primary radiation interacting with matter. One of the main sources of secondary radiation is leakage radiation, which occurs when primary radiation escapes from the intended pathway or device, such as an X-ray tube.

When primary radiation, such as X-rays, collides with surrounding materials such as the patient, equipment, or the walls of a room, it can produce secondary radiation. This interaction can cause the release of secondary photons, some of which may scatter in various directions, contributing to the overall radiation exposure in the environment.

Recognizing leakage radiation as a source of secondary radiation is critical for understanding how to manage and minimize exposure in medical and other settings that involve radiation. It emphasizes the importance of shielding and proper equipment design to contain and control radiation effectively.
