A decrease of approximately _________ mAs will compensate for most destructive pathologies.

An increase in time requires a decrease in which of the following to maintain the same receptor exposure?

If the exposure rate to a body standing 7 feet from a radiation source is 1.5 mGy, what will be the dose to that body at a distance of 8 feet from the source in 30 minutes?

Which of the following groups of technical factors will produce the greatest exposure to the IR?

Which of the four prime factors affect beam intensity reaching the IR?mAtimekVpSID

SID and beam intensity have what kind of relationship?

A radiograph is made with a 36″ SID resulting in a beam intensity of 100 mGy. What will the beam intensity be if the SID changes to 72″?

An x-ray exposure is made using 400 mA, 0.1 seconds, 100 kVp, and a 40″ SID. What is the maximum energy of x-ray photons in the beam?

A technologist makes an exposure using 50 mA at 0.46 s. There is involuntary motion on the image, but the technologist wants to maintain receptor exposure. If the exposure time is reduced to 0.115 s, what is the new mA?

Given 50 mA and an exposure time of 0.5 s, calculate the mAs.
