Gamma-Ray Attenuation to Evaluate Soil Porosity: An Analysis of Methods
Figure 3
Experimental (Exp) and calculated (XCOM) mass attenuation coefficient variation as a function of photon energy . Experimental data for water (a) and sandy and clayey soils (b) were obtained for photon energies of ≈60 keV (241Am) and ≈662 keV (137Cs).
