Abstract
The changes in the surface topology of polyethylene and polycarbonate films irradiated with gamma rays up to 500 kGy doses have been investi gated with Atomic Force Microscopy. The cumulative effect of irradiati on has been followed by analyzing exactly the same region of the surfa ces after every irradiation step. This has been achieved by applying a n addressing operation on the surfaces of virgin polymers. The increas e in surface roughness showed a sudden increase up to 100 kGy dose and remained almost unchanged thereafter. The radiation-induced topologic al changes are found to correlate with the chemical effects of these r ays. (C) 1997 Published by Elsevier Science Ltd.
