Lipid peroxidation by ultraviolet light and high energy alpha particles from a cyclotron.
High energy alpha-particles (approximately 16 MeV) and 254 nm ultraviolet light produced dose dependent linear increase of lipid hydroperoxides in the dried thin film state. For both types of radiation, an inverse dose-rate effect, i.e., a protracted radiation dose was more effective than a shorter, more intense one of larger size, was observed. Ultraviolet light (254 nm) produced higher yields of hydroperoxides in the aqueous liposomal suspension of lipid than in its dried thin film state.
