The classical Yang-Mills radiation computed in the McLerran-Venugopalan model is shown to be equivalent to the gluon bremsstrahlung distribution to lowest (g{sup 6}) order in pQCD. The classical distribution is also shown to match smoothly onto the conventional pQCD minijet distribution at a scale k{sub {perpendicular}}{sup 2}{approximately}{chi}, characteristic of the initial parton transverse density of the system. The atomic number and energy dependence of {chi} is computed from available structure function information. The limits of applicability of the classical Yang-Mills description of nuclear collisions at RHIC and LHC energies are discussed. {copyright} {ital 1997} {ital The American Physical Society}
