The molar volume and FTIR investigations have been used to study the structural properties of the glass system. Optical, UV-visible, absorption measurements were performed also to investigate the transmittance aimed to investigate the performance of the glass system for using as hot cells for shielding windows in nuclear technology. http://pubs.sciepub.com/pmc/2/1/4/pmc-2-1-4.pdf borosilicate glasses FTIR measurements radiation shielding
