A "high radiation" area is any area, accessible to individuals, in which there exists radiation at such levels that an individual could receive in any one hour a dose to the
whole body in excess of:
- 5 millirems
- 10 millirems
- 50 millirems

A 9" input screen and a 1" output screen increases brightness:
- 9 times

A certain x-ray tube at some given kVp delivers 3 milliroentgen per 1 mAs at 40" of distance. At 80 " of distance, the radiation output from the x-ray beam will be:
- 16 mR/mAs
- 8 mR/mAs
- 2 mR/mAs
- 1 mR/mAs - CORRECT ANSWER: should be 0.75.... maybe CORRECT ANSWER:
D?
half distance=4 times the dose double the distance = 1/4 the dose
- / 3
A certain x-ray tube, at some given kilovolt peak (kVp), delivers 4 milliroentgens (mR) per one milliampere-second (mAs) at 40 inches distance. At 80 inches distance, the
radiation output form the x-ray tube in mR/mAs) will be:
- 16
- 8
- 2
d. 1 - CORRECT ANSWER: d. 1
D1 = 40", I1 = 4mR/mAs; D2 = 80", I2 = x 4(40^2) = x (80^2)
- (1600)/6400 = x
1=x

- 5 milliroentgens per hour
- 25 milliroentgens per hour
- 100 milliroentgens per hour
d. 500 milliroentgens per hour - CORRECT ANSWER: d. 500 milliroentgens per hour
All fluoroscopy machines must have an exposure switch that is of a "dead man" type.
This type of exposure switch is one that stops the exposure:
- When the pressure is released
- Automatically
- After a preset time
d. After five minute cumulative time has been reached - CORRECT ANSWER: a. When
the pressure is released
All of the following affect patient exposure except:
- 3 phase generator
