Lead Phosphate Glass Containing Boron and Lithium Oxides as a Shielding Material for Neutron- and Gamma-Radiation

摘要

A glass system with chemical formula: xLi2O– (50_x) B2O3–40PbO–10P2O5 mole % is prepared to be used as radiation shield. The mass attenuation coefficient and half value layer of the glass system to gamma rays have been measured experimentally and compared with those determined from theoretical calculations using the mixture rule of WinXCom program. A database of effective mass removal cross-sections for fast neutrons is also introduced in this work.
