WebFeb 1, 2002 · Abstract. The NIST Electron Effective-Attenuation-Length Database provides values of electron effective attenuation lengths (EALs) in solid elements and compounds … WebSep 30, 2024 · My setup consists of a single gamma-ray source with a spectrum of up to 150keV, a single voxel of Calcium with a density of 1 g/cm3 and a detector. mu = -log (I/I0) / L to recover the attenuation coefficient, L is the length of the voxel. From this simulation I get an attenuation coefficient of 0.833 cm^-1. Web3 Shielding by building materials Conc re te NIST tested eight different concrete mixes, each atthree different thicknesses. The concrete was solid and without any reinforcement.The key findings were: the attenuation increases with higher frequencies the attenuation varies little between the eight mixes humana provider payment integrity disputes
