摘要：

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