What is the main source of scattered radiation in radiography?

The main source of scattered radiation in radiography is the patient. When X-rays are directed towards the patient for imaging purposes, some of these X-rays interact with the tissues of the body. This interaction causes the X-rays to change direction, resulting in the emission of scattered radiation. This scattered radiation can lead to lower image quality and can also contribute to radiation exposure for both the patient and the radiographer.

Understanding the role of the patient as a source of scattered radiation is crucial for implementing effective radiation safety protocols. It emphasizes the importance of proper positioning, shielding, and the use of appropriate imaging techniques to minimize exposure and improve diagnostic efficacy.

In contrast, other sources such as the X-ray machine itself, the radiographer, and the film do not contribute significantly to scattered radiation in the same manner as the patient. The X-ray machine primarily generates the primary beam, while the radiographer and film are involved in the measurement and capture of that radiation, not in the production of scattering from tissue interactions.
