  We investigate the effect of induced massive radiation given off during the
time of collapse of a massive spherically symmetric domain wall in the context
of the functional Schr\"odinger formalism. Here we find that the introduction
of mass suppresses the occupation number in the infrared regime of the induced
radiation during the collapse. The suppression factor is found to be given by
$e^{-\beta m}$, which is in agreement with the expected Planckian distribution
of induced radiation. Thus a massive collapsing domain wall will radiate mostly
(if not exclusively) massless scalar fields, making it difficult for the domain
wall to shed any global quantum numbers and evaporate before the horizon is
formed.
