WebIf the slope of the line of your Aluminum Shielding of C − 14 graph was −.216/ mm, what would be the half-value layer of the Aluminum? Calculate the thickness of the HVL in mm. Enter only the number portion of your answer. Do not include units. A material's half-value layer (HVL), or half-value thickness, is the thickness of the material at which the intensity of radiation entering it is reduced by one half. HVL can also be expressed in terms of air kerma rate (AKR), rather than intensity: the half-value layer is the thickness of specified material that, "attenuates the beam of radiation to an extent such that the AKR is reduced to one-half of its original value. In this definition the contribution of all scattered radiation, other than an…
