A person wearing a _ apron will reduce transmitted
exposure to approximately 99.9% of the incident scatter
dose
1. 1.5 mm Pb equivalent
2. 0.50 mm Pb equivalent
3. 0.25 mm Pb equivalent
,4. 1.0 mm Pb equivalent - ANSWER->2. 0.50 mm Pb
equivalent
If the input phosphor of an image intensifier measures 15
inches in diameter and the output phosphor measures
1.0 inches, the minification gain would be
1. 30
2. 225
3. 175
4. 300 - ANSWER->Minification Gain = {15(2) = 225} input
screen diameter (2) / {1.0 (2) = 1} output screen diameter
(2) = 225/1= 225

2. standardization of electronic patient health data
3. limits PHI to a "need to know.." basis to carry out
medical treatment
4. all the listed answers - ANSWER->4. all the listed
answers
To provide illumination stability of the virtual image
