  We study the radiative energy loss contribution to proton stopping in $AA$
collisions. The analyses is performed within the light-cone path integral
approach to induced gluon emission. We have found that the radiative correction
can fill in partly the midrapidity dip in the net proton rapidity distribution
in $AA$ collisions at $\sqrt{s}\sim 10$ GeV. We argue that at $\sqrt{s}\sim 10$
GeV the net proton fluctuations at midrapidity may be dominated by the initial
fluctuations of the proton flow, which, to a good accuracy, should be binomial.
