Final answer:
The primary source of scattered radiation during a fluoroscopic procedure comes from the patient due to interactions of X-rays with their body.
Step-by-step explanation:
When performing a fluoroscopic procedure, the primary source of scattered radiation is emitted from the patient. This occurs because the X-rays, after being generated from the X-ray source, interact with the patient's body, causing scattering. X-ray photons carry significantly more energy compared to visible light, and this energy has the potential to ionize atoms and damage biological tissues. Therefore, while visible light is also a form of electromagnetic radiation, it is not as concerning as X-rays due to the energy difference. To minimize the hazards of X-ray exposure, techniques such as using shielding, maintaining a safe distance from the radiation source, and reducing exposure time are essential. These measures are utilized to protect both patients and healthcare workers during fluoroscopic and other procedures involving radiation.
