Supernova Remnants (SNRs) are believed to be the main source of Galactic
cosmic rays (CR). The strong SNR shocks provide ideal acceleration sites for
particles of at least 10^14 eV/nucleon. Radio continuum studies of SNRs carried
out with good sensitivity and high angular resolution convey information about
three main aspects of the SNRs: morphology, polarization and spectrum. Based on
this information it is possible to localize sites of higher compression and
particle acceleration as well as the orientation and degree of order of the
magnetic fields, and in some cases even its intensity. All this information,
when complemented with the study of the distribution and kinematics of the
surrounding interstellar gas, results in a very useful dataset to investigate
the role of SNRs as cosmic ray accelerators. In this presentation, I analyze
the radio observations of SNRs and surrounding molecular clouds, showing the
contribution of these studies to the understanding of the role of SNRs as
factories of CRs.
