The dose dependence of swelling in irradiated metals

Abstract
The dose and dose rate dependences of swelling are determined theoretically for metals under different types of irradiation. The simple theory assumes that it is the preferential absorption of interstitials by climbing dislocations that is directly responsible for the swelling. In particular, the different dose dependences observed under ion, electron, and neutron irradiation are explained in terms of the dislocation configurations operative in each case.
