In the present study, the effect of electron-beam irradiation on physicochemical and mechanical properties of polypropylene (PP) syringes was studied. Three irradiation doses (30, 60 and 120 kGy) were applied to all samples. Non-irradiated PP syringes were used as control samples. Electron-beam irradiation caused an increase in the degree of yellowness and in the extractable radiolysis products. A decrease in compression strength and extension at break was the result of electron-beam irradiation on mechanical properties of PP syringes. Minor differences were observed in FTIR spectra, mainly in the region of 1720 cm(-1), corresponding to the absorption of carbonyl compounds. Gas chromatography/mass spectrometry (GC/MS) analysis indicated the formation of a number of radiolysis compounds while a number of compounds initially present in non-irradiated syringes were destroyed by the irradiation. The degradation on polymer properties caused by electron-beam irradiation was less severe than that caused by gamma irradiation. (C) 2006 Elsevier Ltd. All rights reserved. (EN)
