According to NCRP regulations, what is the maximum permissible leakage radiation from the x-ray tube?

The maximum permissible leakage radiation from the x-ray tube is set at 100 mR/h as per NCRP regulations. This limit is established to safeguard both patients and healthcare personnel from excessive exposure to radiation.

The rationale behind this specific threshold is to ensure that the amount of radiation that escapes the protective housing of the x-ray tube remains at a level that is considered safe according to current scientific understanding. By maintaining leakage radiation at or below this limit, the risk of harmful biological effects from exposure is minimized, contributing to overall safety in radiological practices.

The clarity of this regulation underscores the commitment of the National Council on Radiation Protection and Measurements to enforce standards that prioritize health and safety in environments where radiation is utilized.
