Magnetic properties of gamma irradiated single crystals of cholesteryl chloride: An EPR study

► In the present work we have investigated magnetic properties of cholesteryl chloride, which has not yet been studied by EPR. ► We have found out a stable free radical in gamma irradiated cholesteryl ester; cholesteryl chloride. ► It is important to be shown the effect of gamma irradiation on cholesteryl esters.
