Fig. 1

Mass attenuation spectra of water and gadolinium, with a line drawn at 511 keV showing the similar mass attenuation coefficients. Inset shows a close-up of the values at 511 keV. At 500 keV (the last measured point), this difference in μ M is 14.95%. Data has been replotted from tabulated data originally published by Hubbell [9]
