Abstract

The macroscopic effective removal cross-sections for fast neutrons (higher than 104 eV) (åR) are parameter for used characterize the attenuation of fast neutrons in materials. This article interests on shielding radiation properties for borate glass in composition xLu2O3:20Li2O:(80 – x)B2O3 at different concentration (x = 5, 10 and 15 mol%). Furthermore, the macroscopic effective removal cross-section for fast neutron values was also estimated and compared with ordinary and hematite–serpentine concrete. The results obtained can be used to choose the effective shielding radiation material for reducing heat energy into building.
