摘要
引入少量的示踪物氧化钐,磷酸盐玻璃的工艺性能不会发生大的变化,制成玻璃微球的方法可以不变。这种微球经中子活化后,在发生β衰变的同时,还伴随γ衰变,放射出的低能氧化钐后,磷酸盐玻璃微球的化学稳定性得到了很好的改善,进一步提高了使用的安全性,这是一种多功能的内放射医疗玻璃微球。
Introducing a small amount of Sm2O3 can hardly change technological properties of glass,and glass microspheres can be prepared by the same way as usual.When Sm-contained microspheres are bombed by thermal neutrons , β-decay and γ-decay happen emitto γ-rays with lower energy,which can be detected by Γ camera.By using this feature,the location and monitor of the microspheres in the human body may be realized in the clinie practice .Introducing a small amount of Sm2O3 improves significantly the chemical stability of glass microspheres,and enhances their safety in body .They are new kinds of radiltherapeutic glass microspheres, and enhancing their safety in body.
