AB A formalism for the evaluation of the intensity of photon and gluonbremsstrahlung in QED and QCD condensed media is presented whichconsiders general interactions beyond the Fokker-Planck approximation,the angular distribution of the final particles and admits finite orstructured target calculations. The Fokker-Planck results ofMigdal/Zakharov and the BDMPS group are recovered under the adequateapproximations as particular cases. Weinberg's soft photon theorem isshown to saturate the LPM suppression in the soft regime. The angleintegrated intensity under realistic screened interactions is alwayslarger than the Fokker-Planck evaluation and the changes can not beaccounted for by a single definition of the medium transport
