摘要

研究了中能,18,O,8+,离子束辐照胸腺嘧啶N,2,O饱和水溶液时重离子对胸腺嘧啶的影响，利用UV、HPLC、GC、GC-MS、GC-FT-IR等仪器对产物进行了分析，对羟基加成产物、二聚体等十几种产物进行了鉴别，测得不同辐照剂量下胸腺嘧啶的G值分别为0.24和1.14;对重离子辐照与γ射线辐照进行了比较。

Abstract

In this paper thymine (T) irradiated by ,18,O,8+, ion beam in N,2,O saturated aqueous solution was studied. The apparatus of Ultraviolet (UV) ,High Performance Liquid Chromatography (HPLC) ,Gas Chromatography (GC) ,Gas Chromatography - Mass Spectrometry (GC-MS) and Gas Chromatography - Fourier Transformation - Infrared (GC-FT-IR) were used to analyze the products. The hydroxy and hydro adducts and dimers were determined. The G values of products were calculated. The damage of the irradiation of heavy ion beam was more serious than that of γ ray. The mechanism of the irradiation of heavy ion beam on materials was discussed at the end of this paper.
