What is the maximum allowed leakage radiation from the fluoroscopic tube according to NCRP regulations?

The maximum allowed leakage radiation from a fluoroscopic tube, as established by NCRP regulations, is set at 1 milligray per hour at a distance of 1 meter from the tube. This standard is established to ensure patient and occupational safety by limiting exposure to radiation from the equipment that is not intended for direct therapeutic or diagnostic use.

The NCRP guidelines focus on maintaining radiation levels within safe limits to protect both patients and healthcare workers, and achieving this requirement is a critical aspect of radiation safety in medical imaging. This specific limit of 1 milligray/hour at 1 meter helps in minimizing unnecessary radiation exposure, thereby enhancing the overall safety profile of fluoroscopic procedures.

Other listed options do not meet the specific regulatory threshold, indicating a higher potential risk of radiation exposure. Adhering to the NCRP's guideline of 1 milligray/hour helps facilities comply with safety regulations while also ensuring the well-being of patients and medical personnel.
