摘要
电离辐射对生物体构成损伤 ,一是辐射能量传递的直接作用 ,二是通过水在辐解反应中产生的自由基所引起的损伤的间接作用 ,氧化损伤是辐射对机体损伤的重要机制之一。抗氧化物质可以清除自由基 。
Organisms usually can be injured by ionizing radiation,involving two possible mechanisms,one is direct energy tranmission by ionizing,and the other is indirect effect of free radical produced in radiolysis of water.Oxidant damage is one of important mechanisms causing body injury by radiation.Free radicals can be eliminated by antioxidant substances,so they should have effects on radioprotection.
