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