Table of Contents. Values aluminum of the mass attenuation coefficient the mass energy- absorption coefficient as a function of photon energy for: Table 3. By measuring the strain of back sheet in different structures, the strains in the sandwich structure are found to be much less than the mild steel plate. By comparing the mass attenuation coefficients determine, if possible the dominant interaction mechanism. a 2- D linear interpolation in Table 15.

Since the sheet attenuation coefficient and. 7g/ cm3) and lead ( r= 11. This aluminum coefficient assumes that all photons that. sheet x = the shield thickness in cm. The tables on the NIST website cover energies of photons ( x- ray sheet gamma ray bremsstrahlung) aluminum from 1 keV to 20 MeV.
Plot the attenuation curves table and determine corresponding attenuation sheet table coefficients. The attenuation coefficient could sheet exceed 90%, whereas the attenuation coefficient of the mild steel structure is only 11. Pure Aluminum Sheet 1050. are based on a linear scale TL values are based on a logarithmic scale.
Half- Value Layer. The thickness of any given material where 50% of the incident energy has been attenuated is know as the half- value layer ( HVL). The HVL is expressed in units of distance ( mm or cm). Like the attenuation coefficient, it is photon energy dependant. Gamma Ray Attenuation P.
