Which type of personnel is most likely to be affected by Compton scatter during fluoroscopic procedures?

The question pertains to the effects of Compton scatter, a type of radiation scattering that can occur during fluoroscopic procedures. Compton scatter is primarily a concern for individuals who are in close proximity to the source of radiation and are exposed to it during the procedure.

Radiology technicians are frequently positioned near the fluoroscopy machine while they assist in procedures and manage the equipment. As such, they are more likely to receive scattered radiation from the patient as the x-rays interact with the body and disperse in various directions. This exposure can significantly increase their radiation dose, even with protective measures in place.

Patients receiving x-rays, while certainly exposed to the radiation necessary for imaging, are not typically at risk from Compton scatter in the same manner, as they are the source of the x-rays rather than a bystander. Similarly, radiologists, who usually interpret images from a distance, and nurses, who may be involved in certain aspects of the procedure, generally spend less time directly in the path of scattered radiation compared to technicians involved in the hands-on aspects of the fluoroscopic procedure.

Therefore, understanding the roles and positions of personnel during fluoroscopy highlights why radiology technicians are the most affected by Compton scatter in these scenarios.
