What is the maximum intensity of the fluoroscopic beam at the tabletop?

The maximum intensity of the fluoroscopic beam at the tabletop is defined to ensure patient protection and limit radiation exposure during fluoroscopic procedures. The current regulation permits a maximum intensity of 10 R/min at the tabletop. This standard is established to balance the need for effective imaging with the need to protect patients from unnecessary radiation exposure.

This limit is significant in the context of radiation safety, as it reflects a commitment to safeguarding both patients and medical personnel by maintaining exposure levels within safe limits. The choice of 10 R/min corresponds to guidelines from authoritative bodies focused on radiological health, such as the National Council on Radiation Protection and Measurements (NCRP) and the American College of Radiology (ACR).

The other choices represent higher exposure limits that exceed the regulatory standards designed to minimize radiation risks. Thus, they would not align with established safety protocols for fluoroscopic imaging.
