Abstract:
Large quantities of dismantled cathode ray tube (CRT) wastes from used computer monitors and TV sets have become a major environmental risk in the world. New disposal and re-use approaches are needed to address the risk. The lead equivalent, chemical composition and sintering characteristics of the glasses from dismantled color CRTs were tested by QH16 Χ,γ-ray standard dosimetry device, XRF, ICP, XRD and ash fusibility furnace, and the results were compared with those of steel, iron ore and barite et al.. The mass attenuation coefficients, X-ray and γ-ray absorption, and radiation protecting capabilities of the glasses were discussed. The results showed that the constituents of the glasses, such as Pb, Ba, Sr, Sb, Ce, Zn, were effective for the radiation protection. The preparing of the radiation shielding materials with these wastes using sintering treatment technique could be an effective approach to their pollution control and utilization.
