DOSE EFFECT OF keV IONS IRRADIATION ON ADENINE AND CYTOSINE
keV离子辐照固态腺嘌呤与胞嘧啶的剂量效应研究

Dose effect of adenine and cytosine irradiated by 20 keV N and Ar was studied. It was found that N can damage more base molecules than Ar at the same dose, and cytosine shows a higher sensitivity than adenine irradiated by the same kind of ion. G-values of the damaged bases were calculated, and they presented a decreasing tendency with the dose increasing. The influence of radical eliminator on dose effects was investigated, and preliminary explanations to all these results were provided as well.
