By using the Goldstone-boson equivalence theorem, the {ital leading} electroweak radiative corrections to the tree-level process {ital t}{r arrow}{ital W}{sup +}{ital b} are obtained in three different limits: (i) {ital m}{sub {ital H}}{gt}{ital m}{sub {ital t}}{gt}{ital M}{sub {ital W}}, (ii) {ital m}{sub {ital H}}={ital m}{sub {ital t}}{gt}{ital M}{sub {ital W}}, and (iii) {ital m}{sub {ital t}}{gt}{ital m}{sub {ital H}}{gt}{ital M}{sub {ital W}}. Recently, several groups have done the same calculation without using the equivalence theorem approach and obtained slightly different results. We compare our results with these previous works.
