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.

Which of the following techniques would produce the same receptor exposure as 500 mA at 0.03 s?

An intensity of 200 mGy is recorded at a distance of 40″. If the same technical factors are used, what will be the intensity if the distance is increased to 80″?
