Tenth value layer equation
Web17 Sep 2024 · In the Equation (2), µ is the Linear Attenuation Coefficient (LAC), N A is the Avogadro number, M and σ tot are the atomic mass and total microscopic cross section of the sample, and W k is a weight fraction of the k th element in the fabricated brass composite sample. Derived from this basic quantity, mfp (mean free path) and HVL (half … WebThis concept ties into the shielding formula noted above, however, it is "more basic" in its approach. To have an attenuator that has a value of 1 HVL means that it reduces the intensity of radiation by 1/2. Similar to the value x in the formula above where the density of the shield determines the HVL. HVL is also determined by the amount of ...
