2) Original x-ray beam intensity
3) The intensity of the transmitted radiation (as measured by the detector)

To perform an attenuation calculation, it is necessary to know the thickness of the part (to understand how much material the x-ray beam is passing through), the original x-ray beam intensity (to know the starting intensity before any attenuation), and the intensity of the transmitted radiation (to measure how much intensity is left after the beam has passed through the part). These three pieces of information are essential to calculate how much the x-ray beam has been attenuated by the part.
