Half-life and yield of hydrated electron in water-in-oil microemulsion of cetyl trimethylammonium bromide-water-1-pentanol-cyclohexane system has been studied. Dose distribution calculation suggests scavenging of electrons that are generated in cyclohexane by water pools and hydroxyl radical generation by direct water radiolysis only. Dose distribution, half-life of e-aq,generation and solvation of e-aq in this system and its comparison with other systems have been discussed.
