Abstract :

Abstract: Objectives: The main aim here is to describe the dependence of the relative biological effectiveness (RBE) of proton irradiation of V79 cells on survival. Method: This is done by fitting survival curves of various proton energies to the Linear Quadratic equation, The RBE values at survival levels of 0.2 - 0.9 were calculated using 60Co gamma ray as a reference radiation. Results: An equation with four free parameters is suggested to describe the RBE-vs.-Survival relationship. Conclusion: RBE -vs- Surviving fraction curves were adequately fitted to an exponential plus cubic function with four free parameters. Two of those parameters are LET dependent. The rest nearly constants.
