"WebRemember, the definition of the half value layer (HVL) is when the exposure is 1/2 of what it is without any material. Even if we don’t have a measurement that’s exactly at the half value layer (i.e. the perfect thickness of materials to stop have the x-rays) we use curve fit to estimate the HVL. This is demonstrated in the figure. " - Half value thickness calculator
