The radio continuum emission was investigated at 22 GHz of a sample of southern peculiar galaxies, since the peculiarities are a possible evidence of radio emission. A sample of 24 peculiar galaxies was observed with the antenna of the Radio Observatorio de Itapetinga (ROI-INPE). The observational technique used was to scan through the source in right ascension; the adopted sensibility limit was 3 rms. Three galaxies were detected as radio sources for the first time and the fluxes of 4 well known radio sources in other frequencies were measured at 22 GHz. The obtained flux densities were in the range of 0.5 to 4.5 Jy, showing that the instrument and the observational technique were satisfactory for the observation of weak sources.
