Leakage radiation
• Intensity can’t exceed L = 100 mR/hr at 1 m
when tube is operated at its leakage
technique factors
– maximum potential for continuous operation
kVp max (typically 135-150150 kVp, or 50 kVp for
mammography)
– I max is the maximum continuous tube current
possible at kVp max . Note that this is usually a
low mA, not typical of clinical radiography.
