Braking (Bremsstrahlung) as well as characteristic X-Rays. If all the
materials are low Z, the characteristic X-Rays will be very low energy
level.
Brems will be in a continuous spectrum, up to the maximum value of the
electron energy.
Both types are considered secondary radiation, so they will be isotropic not
directional.

If anyone has better data on this last point, correct me please.
