  Almost 60% of the B2 low luminosity radio galaxies have been observed with
the Hubble Space Telescope. We present an analysis of the dust features, which
are often present in the form of circum-nuclear disks or lanes, and show that
there are correlations between radio source and dust properties. It is found
that nearby radio sources in which a jet has been detected tend to have dust
more often than sources without jets; the dust is often in the form of disks or
lanes. Moreover the radio jets are close to perpendicular to the disk or lane
in the weaker radio sources (with P < 10^{24} W/Hz). In stronger sources the
orientation effect appears to be weak or even absent. Also the dust masses
found in the weaker radio sources are smaller than in the stronger ones (log
M/M_sun ~ 3 against 5 respectively). More generally it appears that there is a
correlation between dust mass and total radio power (for those sources in which
dust has been detected); we show that this correlation is not induced by
redshift.
