The correlations between the UV galactic background (after subtraction of direct starlight), the neutral hydrogen HI, the extinction and the 100 μm emission are discussed for high galactic latitudes mainly based on a new analysis of the D2B satellite data. While clear correlations exist between UV and the other quantities, indicating that most of the UV galactic background is starlight scattered by interstellar dust, these correlations are less tight than the correlation between HI and the 100 μm emission. Localized UV excesses are shown to exist and are due in some cases to 2-photon emission by ionized gas. The quantitative interpretation of the UV galactic background in terms of dust properties is discussed, and it is shown that both the galactic model and the clumpiness of interstellar radiation may affect the results considerably.
