Abstract : In the first part polymers were divided into two groups according to the nature of their predominant activity under the influence of radiation, into polymers which are predominantly cross-linking or degrading. The activity mentioned proceeds even at relatively small doses, although doses up to over 0.1 Mrad are necessary to produce substantial changes. In reviewing the resistance of some materials to radiation, mention should always be made of the basis for the criteria according to which resistance is determined and under what conditions the polymer radiation occurred. The choice of a suitable criterion is very important, for in some polymers radiation resistance may differ by multiples of thousands from different points of view.
