| Abstract | The elastic and radiation shielding properties of lead-recycled cathode ray tube (CRT) glass were investigated in orderto study the possible reduction in the use of toxic lead oxide glass by partial replacement using CRT glass waste. The elasticproperties of lead-recycled glass were studied using the pulse-echo ultrasonic technique and it was found that the elasticproperties varied with CRT content in the glass. This indicated the existence of some modifying cations in the CRT. Theradiation shielding properties of the glass were also studied by means of the calculated mass attenuation coefficient, mean freepath, and half-value layer using the WinXCom program. The addition of CRT glass was found to deteriorate the radiationshielding properties of lead glass. However, lead-recycled CRT glass still exhibited better radiation shielding properties than theconventional barite concrete. Therefore, lead-recycled CRT glass can be a potential candidate for radiation shielding applications. |
