A new method for recycling the glass of Cathode Ray Tubes (CRTs) is presented in this paper. The glass from CRTs is suggested to be used as row materials for producing radiation shielding glass. Cathode ray tubes glass contains considerable amounts of environmentally hazardous toxic waste namely heavy metal oxides such as lead oxide (PbO). This makes CRTs glass a favorable choice to be used as row material for Radiation shielding materials, as heavy metal oxides increases its density, which make the produced glass nearly equivalent to commercially available shielding glass. CRTs glasses have been characterized to determine the heavy oxides content, density, refractive index, and radiation shielding properties for different gamma rays energies empirically by using the source Co-60 and theoretically by using the code XCOM. The measured and the calculated values were in a good compatibility. The effect of irradiation on the transparency for each part of the CRTs glass has been studied. Results showed that some parts of CRTs glass are more resistant to radiation than others. The study has shown that the glass of cathode ray tubes can be recycled as a radiation shielding glass at least in some applications.
