Scientific paper

We present ISOPHOT observations in the 60-200 μm wavelength range of a sample of high-latitude interstellar regions. A well-defined 150-200 μm emission relationship is followed by all regions, indicating the far-infrared emission of the large grains is a unique function of the dust column density. We find that the 200 μm emission per AV does not drop with temperature suggesting a relative increase in emissivity of the large grains at lower temperatures. The emission of the small dust particles shows significant variations from region to region, especially at low surface brightness level. These variations cannot be accounted completely by temperature changes and the results suggest variations in the relative abundance of smaller grains.
