  We calculate the angular power spectrum of the galactic synchrotron radiation
induced by the small scale fluctuations of the magnetic field and the cosmic
ray electron density. Using the observed interstellar magnetic field spectrum,
which is consistent with the Komolgorov turbulence model at the relevant
scales, we find that $C_l \propto l^{-3.7}$. We estimate the cosmic ray
electron density fluctuation spectrum with an injection-diffusion model, the
shape of the angular power spectrum in this model depends on the correlations
between the injection sources. For Poisson distribution of sources, $C_l
\propto l^{-4}$. We discuss the implications for the interpretation of cosmic
microwave background (CMB) data and the impact on future 21 cm tomography
experiments.
