To evaluate the radiation Stability of the extraction agent applied to the solvent extraction process, energy transfer process to extraction solvent was estimated by using a Monte Carlo Particle and Heavy Ion Transport code System, PHITS. Our results suggest that low LET radiation will be dominant influence on absorbed dose. It was demonstrated the degradation yields of the extractant could be evaluated by reference to the experimentally obtained G-values.
