Abstract
Calculated and measured data are presented for the leakage from a 150 kVp tube in a 150 kVp diagnostic-type protective tube housing when operated at its maximum continuous rated current at 85, 100, 125 and 150 kVp. When the tube is operated at its maximum continuous rated current at less than its maximum rated voltage, the decrease in thickness of the secondary barriers as a result of the reduced tube housing leakage will not be more than one half-value layer. In most cases the lead (7439921) thickness specified for an installation will be the commercially available sheet lead thickness greater than the calculated value. Where lead is specially rolled for a calculated thickness it may be advisable to use the lower leakage in calculating the barrier thickness providing the roller thickness tolerance is less than one half-value layer.
