Explanation:
Detailed explanation-1: -The increase in x-ray tube voltage increases the amount of radiation coming out of the x-ray tube, as well as the average photon energy (i.e., increased penetration). Accordingly, the tube current exposure time product value (mAs) is reduced to 36 mAs; whereas at 60 kV, the value was much higher (141 mAs).
Detailed explanation-2: -As the quantity of x-rays is increased (mAs), the exposure to the image receptor proportionally increases. As the mAs is increased, the quantity of radiation reaching the IR is increased. As the mAs is decreased, the amount of radiation reaching the IR is decreased.
