Abstract:The risk of di (2-ethylhexyl) phthalate (DEHP) migration from plasticized poly (vinyl chloride) (PVC) is an important issue for patients.We present a study on the effect of gamma radiation on the migration of DEHP from plasticized PVC into air and PVC as a function of time (0-28day) at 75°C.The samples were irradiated at dose of 25 kGy using a 60Co gamma radiation source.The change of weight loss at 75°C was studied as a function of time.Diffusion coefficient of samples was calculated,it was found that the dif… Show more
