What is the minimum source-to-skin distance for mobile fluoroscopic units?

The minimum source-to-skin distance for mobile fluoroscopic units is 30 cm (12 inches). This distance is established to ensure patient safety and minimize exposure to radiation during procedures. The regulation is based on the principle that increasing the distance from the radiation source reduces the intensity of exposure due to the inverse square law of radiation. By maintaining a minimum distance of 30 cm from the source to the patient’s skin, healthcare providers can effectively decrease the potential for harmful effects associated with radiation exposure, such as tissue damage or increased cancer risk.

This distance is crucial in protecting both patients and healthcare personnel during fluoroscopic imaging procedures, as mobile units are often utilized in a variety of dynamic clinical settings. Adhering to this minimum requirement is part of best practices in radiology and contributes to safer healthcare delivery. Thus, understanding and following this guideline is key for those operating and utilizing mobile fluoroscopic systems.
