Question: what is the maximum amount of leakage radiation that can escape from an x-ray tube?
Answer: The X-ray tube housing must be of a diagnostic type. A “diagnostic type tube housing” is the type of tube housing constructed so that leakage radiation does not exceed 100 mrems, or 1mSv, in any one hour at a distance of 1 meter (39.37 inches) from the X-ray tube.
