Impact of $ \mathrm{Eu_2}\mathrm{O_3} $ and $ \mathrm{Er_2}\mathrm{O_3} $ on the gamma radiation shielding performance of $ \mathrm{B_2}\mathrm{O_3} $+CaO+ZnO+BaO+$ \mathrm{Eu_2}\mathrm{O_3} $ + $ \mathrm{Er_2}\mathrm{O_3} $ glass system [PDF]

Nuclear Technology and Radiation Protection
In this study, four rare earth-doped BaO-ZnO-CaO-$ \mathrm{B_2}\mathrm{O_3} $ glass samples were prepared using melt-quenching technique. The density of the glass was determined using Archimedes' method and found in range 3.28-3.72 $ gcm^{-3} $.

Apparent linear attenuation coefficients in phase contrast X-ray tomography [PDF]

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2011
In the inline phase contrast x-ray tomography the reconstructed apparent linear attenuation coefficient values may be greatly larger than sample's linear attenuation coefficients or even be negative. In this work we present a general formula to quantitatively relate the apparent linear attenuation coefficient values in cone-beam phase contrast ...
