What is the leakage radiation limit for XThe leakage radiation from the diagnostic source assembly measured at a distance of 1 meter in any direction from the source shall not exceed 0.88 milligray (mGy) air kerma (vice 100 milliroentgen (mR) exposure) in 1 hour when the x-ray tube is operated at the leakage technique factors.
Which NCRP regulation is used for leakage radiation from the x1. leakage radiation. NCRP Report No. 102 states the exposure switch on mobile radiographic units shall be so arranged that the operator can stand at least 2 m (6 feet) from the patient, the x-ray tube, and the useful beam.
What is the leakage radiation limits for the tube 1'm from the housing?(1) The leakage radiation from the tube housing assembly, measured at a distance of one meter in any direction from the source, must not exceed 100 milliroentgens in one hour when the X-ray tube is operated at its leakage technique factors.
What amount of leakage radiation is acceptable at a distance of 1'm from the protective housing?Leakage radiation must be less that 1 mGy_a/hr (100mR/hr) at a distance of 1m from the protective housing. Control Panel must indicate the conditions of exposure and indicate when the x-ray tube is energized.
