Studies on Effects of Low Energy Heavy Ion Implantation and Model Simulation
-
摘要: 低能重离子注入生物体是20世纪80年代中期发展起来的一种诱变手段, 在诱变育种和放射医学等领域有巨大的应用前景。 物理辐照的剂量与存活率之间的关系是辐射生物学效应的最重要的关系之一, 低能离子与生物体相互作用的剂量存活率曲线表现为特殊的马鞍型。 介绍了低能重离子的马鞍型剂量存活率效应及其数学模型, 并探讨了模型拟合中存在的一些问题。
Lowenergy heavy ion implantation is an organism mutation method developed in middle of 1980s, which has a potential application in breeding and radiation therapy. The dosesurvival curve is a characteristic effect in radiobiology. Implanted with lowenergy heavy ions, organisms could manifest a Saddlelike dosesurvival curve. In this article, the Saddlelike dosesurvival effect and its modeling has been described, and several topics in model simulation are discussed.-
