Name a common source of radiation during imaging procedures.

Scatter radiation from the patient is a commonly recognized source of radiation during imaging procedures because it results from the primary x-ray beam interacting with tissues within the patient’s body. When x-rays penetrate the patient, they not only help create an image but also cause some of the radiation to be deflected or scattered in different directions. This scatter radiation can potentially expose medical personnel and others nearby to radiation, which is why proper shielding and safety measures are critical during imaging procedures.

The reasons for other sources of radiation may not be the most relevant in the context of the question. Ambient environmental radiation is always present but does not arise directly from the imaging procedure. Radiation from imaging equipment refers to the intended primary beam that is directed towards the patient to create the image but is not considered a common source of unintentional exposure. Similarly, radiation from radiology staff would typically result from their proximity to the imaging process rather than being a direct source created during the imaging itself.
