  The measurement of direct photons in s(NN)**1/2 = 200 GeV p+p and Au+Au
collisions is presented. The signal is compared to NLO pQCD calculations,
which, in case of Au+Au, are scaled with the number of underlying
nucleon-nucleon collisions. The agreement of the calculation with the data in
both cases confirms the scaling of hard processes with the number of
nucleon-nucleon collisions and supports the explanation of the earlier-observed
pion suppression as a final-state effect.
