【摘要】 本文介绍了中国科学院辐射化学开放研究实验室（ＳＲＣＬ）在ＤＮＡ、组蛋白和富里烯等的辐射和光化学与物理的前沿研究方面的现状及展望．应用脉冲辐解和激光光焊技术协同ＥＳＲ研究了ＤＮＡ、组蛋白和富里烯等辐解和光解的原初过程及其后续效应机理，电荷转移、激发能转移和氢原子转移等的动态过程，中草药中存在的天然抗氧化剂对ＤＮＡ辐射损伤的保护效应及清除氧自由基的机理，新型低毒放射增散剂的研究等，取得了具有我国特色的多方面研究成果．更多还原

【Abstract】 several novel achievements of the frontier research on radiation chemistry of DNA, histones and fullerence etc. in SRCL are introduced. Using pulse radiolysis and laser flash photolysis techniques in combination with ESR studies charge transfer, excitation transfer and H-atom transfer process have been explored. The polyfunctional protection effect including radioprotection and scavenging oxy radical exerted by several kinds of naturally occurring phenolic antioxidants distributed among chinese herbs have been studied.更多还原
