At a distance of 3 ft. from the head of the table, the radiographer will receive how much exposure during fluoroscopy?

The correct answer indicates that at a distance of 3 feet from the head of the table during fluoroscopy, a radiographer will receive an exposure of 50 mR/hr. This value aligns with established radiation safety guidelines and the inverse square law, which states that radiation intensity decreases with the square of the distance from the source.

In practical terms, at a distance of 3 feet from the fluoroscopy source, the radiation exposure will depend on how the equipment is designed and calibrated, alongside the operational parameters being used. A measurement of 50 mR/hr is reasonable and reflects typical operational conditions for a radiographic setup, allowing for adequate patient imaging while maintaining safety for the personnel involved.

Understanding this exposure level is crucial for radiographers as they must be trained not only in the technical aspects of fluoroscopy but also in the principles of radiation safety to minimize their own exposure while ensuring optimal patient care.
