Abstract
Polarization maps of a sample of spatially resolved low-z radio galaxies show that there are two components to the polarization. One component is intrinsic to the nucleus, while the other is restricted to elongated or fan-like areas which are centred on the nucleus and are cospatial with the known, extended emission-line regions. The orientation of the nuclear polarization is at large angles to the orientation of the extended polarization and approximately parallel to the main extended structures seen on our polarized intensity maps. These results can be explained in terms of a simple scattering model, although we cannot completely rule out contributions from other mechanisms, such as dichroic extinction by aligned dust grains
