What is the minimum source-to-skin distance (SSD) required for mobile fluoroscopic units?

The minimum source-to-skin distance (SSD) required for mobile fluoroscopic units is 30 cm. This regulation is in place to help minimize radiation exposure to the patient and medical staff. Keeping the source of radiation at a greater distance from the skin significantly reduces the intensity of radiation experienced by the patient, as dictated by the inverse square law.

Using mobile fluoroscopy, practitioners must adhere to this distance to ensure safety standards are met, thereby protecting the patient's skin from excessive radiation exposure. The 30 cm requirement is a standard guideline established by health and safety regulations in radiology, reflecting extensive research on the impact of radiation dosage at varying distances.

In context, other distances mentioned, while they may represent different rules for other radiological equipment or practices, do not align with the established minimum for mobile fluoroscopic units specifically. Thus, 30 cm is the optimal distance chosen to balance effective imaging capabilities with safety protocols.
