Integral effect of radiation swelling
The model of radiation pore has been examined when its radius is more than critical one. The experimental evidence of weak dependence of pore concentration on the dose makes it possible to connect a separate pore growth to the swelling integral effect. The description of growing pore kinetics takes into account vacancy and interstitial atom flows to a pore. The calculations indicate that in wide range there should be linear dependence of the swelling effect on the dose which goes in line with the experiment data.
