TBP-DPPP两元体系辐射保护效应研究

Study on Radiation Protection Effect in TBP-DPPP Binary System

本文报道磷酸三丁酯(TBP)-苯基膦酸二苯酯(DPPP)两元体系在γ-辐射作用下 DPPP 的辐射保护效应(a值),测定了该体系各类主要辐解产物的 G 值与 X_(DPPP)(DPPP mole 分数)的关系,并按 WAS 方程计算了 DPPP在两元体系中的辐射保护效应α值,还与其他辐射保护剂(苯、TOA、DBPP、DBBP)**的α值作了对比,表明DPPP 具有最大辐射保护能力。

The present paper reports the radiolysis of diphenyl phenylphosphonate(DPPP)and the radiation protection effect of DPPP in TBP-DPPP binary system.The correlation of G values of various products found in irradiated binary mixture with the mole fraction of DPPP(Xs)is determined.The protection efficiency α value of DPPP was calculated accordng to WAS equation,and compared with that of other protection agents such as benzene,TOA,DBBP,DBPP.
