  We present a computation of QCD next-to-leading order corrections to the top
production and decay process at linear colliders. The top quarks are allowed to
be off-shell and the production and decay subprocesses are treated together,
thus allowing for interference effects. Real gluon radiation effects as well as
virtual corrections are evaluated. The framework employed for this computation
is the double pole approximation (DPA).The results discussed include studies of
the gluon radiation properties, interference between production- and decay-
stage radiation, and top mass reconstruction.
