As a professional radiographer, the practice of ALARA requires you to :: restrict the XR beam to the clinical area of interest The factors that affect XR emission under the direct control of the radiographer are called_ factors :: prime Milliamperage-second (mAs) directly affects all of the following EXCEPT :: beam quality The factors that directly affect XR quantity are :: mA & filtration The factors that directly affect XR quality are :: kVp & beam filtration If 1 coulomb is equal to 6.3 x 10(18) electron charges, how many electrons flow from cathode to anode 1 second :: 6.3 x 10(18) If 1 ampere equals a flow of 6.3 x 10(18) electrons per second, how many electrons flow from cathode to anode in 1 milliampere? :: 6.3 x 10(15) As the mA doubles, the number of electrons flowing from cathode to anode :: increase 2-fold The product of tube current 7 exposure time is equal to :: XR beam quantity In order to increase radiographic film density by 40% the radiographer would :: change the mAs from 15-21 mAs
