Which object is considered the most important source of scatter radiation?

The most important source of scatter radiation is the patient. When X-rays are produced and directed toward the patient for diagnostic imaging, a fraction of those X-rays do not pass straight through the body. Instead, they interact with tissues and structures within the patient, leading to scattering of the radiation in different directions. This scattering can result in radiation exposure not only to the patient, but also to healthcare workers and anyone else in proximity to the procedure.

While other objects, such as control booth walls, the X-ray table, and Bucky-slot cover, can contribute to scatter radiation to some degree, they do not possess the same level of interaction with the primary X-ray beam as the patient does. The patient is, therefore, the primary source of scatter radiation in medical imaging, making it crucial to implement proper shielding and protective protocols in the X-ray environment to minimize exposure.
