The neutron flux in a reactor is analogous to the of a vehicle.

Using high mAs can compensate for insufficient x-ray beam penetrability.

Which of the following can cause quantum mottle? 

An image with few shades of gray exhibits: 

From an original technique of 40 mAs at 98 kVp, which of the following techniques would increase subject contrast in the remnant x-ray beam while at the same time maintaining overall exposure intensity to the image receptor plate? 

Which of the following factors primarily controls subject contrast?

A radiographer takes an initial radiograph using the technical factors of 50 mA at 0.46 seconds. There is involuntary motion on the radiograph, but the radiographer wants to maintain IR exposure. If the exposure time is reduced to 0.115 seconds, what is the new mA? Show your work and include the correct answer units.  

A cross lateral hip x-ray was taken using 78 kVp and 60 mAs. The proximal hip was under penetrated which caused the resulting image to be underexposed. What new technique would demonstrate increased penetration on the radiograph and double the image receptor exposure? Round to the nearest whole number and include the correct answer units.

Match the following exams with the appropriate minimum kVp level to penetrate the part:

Which of the following technical factors would produce a radiograph with the shortest gray scale?
