Gamma-Ray Attenuation-Coefficient Measurements

Abstract
Total γ-ray attenuation coefficients have been measured at nine energies in the range of 88 keV to 2.75 MeV for the following elements: Be, C, Mg, Al, S, Ti, Fe, Ni, Cu, Zn, Zr, Nb, Mo, Ag, Sn, La, Gd, Hf, W, Au, Pb, Th, U, and Pu. Radioactive isotopes were used as sources of monoenergetic γ radiation in a narrow-beam-collimated geometry. Experimental errors are less than 1%.
