The radiation degradation yield of -carrageenan irradiated at atmospheric conditions, in vacuum and at 1% aqueous solutions was determined by GPC. UV-Vis characterization of irradiated -carrageenan for all irradiation conditions indicated a UV-Vis peak at 260nm. The rate constant of reaction of OH radicals with sonicated and irradiated -carrageenan with decreasing molecular weights were determined using e-beam pulse radiolysis.
