Abstract The Ohio State University 260-ft radio telescope has been used to conduct a survey of radio emission from clusters of galaxies and their surrounding regions. Beamwidths are 10 min of arc in right ascension by 38 min of arc in declination at 1415 Mc/sec. The observational results of the well-known nearby clusters of galaxies (Coma, Perseus, Virgo and Pegasus clusters) and some distant clusters are discussed. Radio spectra of the component radio sources in the clusters have been assembled. From a study of the results of the present observation and the existing published data by others, the following conclusions are obtained: (1) radio emission from a cluster of galaxies is always dominated by emission from one or more peculiar radio galaxies in the cluster, (2) there are very few clusters of galaxies in which more than one member galaxy has been identified with a radio source (Perseus Cluster, and Virgo Cluster), (3) clusters in which more than one radio source has been found are very few (Coma, Perseus, Virgo, Pegasus, Al 19) and (4) the individual spectra of the component radio sources in a cluster differ significantly.
