  The spectrum of emitted gluons from the process $\mathrm{gg\rightarrow ggg}$
has been evaluated by relaxing some of the approximations used in earlier
works. The formula obtained in the present work has been applied to several
physical quantities. A general expression for the dead cone of gluons radiated
by virtual partons has been derived. It is observed that the suppression caused
by the high virtuality is overwhelmingly large as compared to that on account
of conventional dead-cone of heavy quarks.
