Abstract
A formal derivation of the sink strengths to be used in point defect rate theory is presented. Previous models that have been invoked for the approximate evaluation of these parameters are discussed. It is shown that the effective medium approach, as introduced earlier by us, constitutes the best available approach for steady state problems. Sink strengths for voids, straight (and parallel) dislocations, dislocation loops and grain boundaries are considered. It is shown that most recent criticisms of the effective medium method are groundless.
