Scientific paper

We have applied the "Synthetic Field Method" on a sample of ~20 nearby
galaxies in order to determine the opacity of their disks. We present
preliminary results on the radial dependence of cold dust absorption for 3
examples. The spirals NGC4535 and NGC4725 show significant absorption at a
half-light radius. UGC2302, a LSB galaxy, shows much less opacity.
