摘要

已经报道，用磷酸三丁酯作“探针”检测正己烷在,60,Co γ辐照下激发态的,G,值。本工作研究正己烷-磷酸三丁酯体系,G,(DBP+MBP,）与剂量的关系，得到剂量外推为零时正己烷敏化磷酸三丁酯的曲线，推导了敏化公式，理论和实验相吻合。求得外推剂量为零时，正己烷在,60,Coγ辐照下形成的两种激发态的,G,值分别为1.0±0.1和0.4±0.1。

Abstract

It has been investigated that TBP labeled with ,32,p was used as a probe for detecting the excited species of n-hexane produced under γ irradiation of ,60,Co. This paper studies the relationship between the G,(DBP+MBP), and dose of the binary system of n-hexane—TBP. In the condition of extrapolating the dose to zero, the curve and the kinetic equation of sensitization of TBP by n-hexane have been obtained. Theoretical calculation was in harmony with experimental results.,It has been found thatTBP can be sensitized by two species of excited state of n-hexane. The ,G, values of excited n-hexane species equal 1.04 and 0.4 respectively and the life time can be estimated by diffusion controlled rate constant, τ,1,=0.3×10,-9, τ,2,= 0,.,7,×,10,-9,.
