We present millimeter-wave observations obtained by the BOOMERANG (Balloon Observations Of Millimetric Extragalactic Radiation ANd Geophysics) experiment of Galactic emission at intermediate and high ( b < -20°) Galactic latitudes. We find that this emission is well correlated with extrapolated dust maps and is spectrally consistent with thermal emission from interstellar dust (ISD). The ISD brightness in the 410 GHz map has an angular power spectrum c l ~ l -β with 2 ≲ β ≲ 3. At 150 GHz and at multipoles l ~ 200, the angular power spectrum of the IRAS -correlated dust signal is estimated to be l ( l + 1) c l /2π = 3.7 ± 2.9 μK 2 . This is negligible with respect to the cosmic microwave background (CMB) signal measured by the same experiment l ( l + 1) c l /2π = 4700 ± 540 μK 2 . For the uncorrelated dust signal, we set an upper limit to the contribution to the CMB power at 150 GHz and l ~ 200 of l ( l + 1) c l /2π < 3 μK 2 at 95% CL.
