Gluon radiation is an important mechanism for parton energy loss as the parton traverses the quark gluon plasma (QGP) medium. We studied the gluon emission in QGP using AMY formalism. In the present work, we obtained gluon emission amplitude \bf F(\bf h,p,k) function, which is a solution of the integral equations describing gluon radiation including Landau-Pomeranchuk-Migdal (LPM) effects, using iterations method. We define a new dynamical scale for gluon emission denoted by x. The gluon emission rate is obtained by integrating these amplitude function over \bf h. We show that these obey a simple scaling in terms of this dynamical variable x. We define the gluon emission function g(x) for gluon radiation for the three processes g→ gg, q→ gq and g→ qq. In terms of this g(x) function, the parton energy loss calculations, due to medium induced gluon radiation, may become simplified.
