摘要
自行研制了辐解气体收集器,对该收集器进行了密封性检验,并利用检验合格的收集器及气相色谱对废树脂水泥固化体的耐γ辐照试验及辐解气体进行了检测。实验结果表明:当累积剂量为10^5Gy时,可检测到6种辐解气体,其中H2占34.77%-49.75%。因此,当放射性废树脂及放射性废树脂水泥固化体贮存和处置时,必须关注贮存与处置期间产生的辐解气体。
Airproof steel container for measurement of radiolytic gas produced from resin waste solidified in cement were manufactured and tested. Waste resin was sealed in container and irradiated by γ-rays at room tempera- ture with 106 Gy. Qualitative and quantitative analysis of gaseous products produced from irradiation were carried out by using gas chromatography. Six kinds ofradiolytic gas can be detected and the yield of H2 is 34.77%-49.75%. The radiolytic gas must be concerned when the resin waste or resin waste solidified in cement is stored or treated.
