"mA x t = mAs (strictly mA.s but the "." is always omitted)600 mA x 0.1 s = 60 mAs"
"50 mA x 0.2 se = 10 mAs is equal to 300 mA x 0.03 s = 10 mAs"
"50 mA x 0.2 se = 10 mAs is equal to 300 mA x 0.03 s = 10 mAs"
"It is due to this law that radiographers will have to take into consideration all other factors (mA, focal spot, source image receptor distance (SID), kVp) to reduce time to avoid motion blur."

"The reciprocity law "
"An increase in tube current (mA) results in a higher production of electrons that are inside the x-ray tube which will, therefore, increase the quantity of x-radiation; more radiation will mean more photons reaching the detector and hence apparent structural density will decrease, yet the signal intensity will increase. The time factor (s) is a measure of the electrons production duration in the tube; meaning 's' prescribes how long mA will last."

"Increasing either the current or time will increase the quantity of radiation; therefore the amount of radiation in an examination is represented as mAs."
