We test the prediction of Hamilton and Helfand (1993ApJ...418...55H) that faint radio selected galaxies are a new class contributing to the diffuse X-ray background (XRB) radiation. The test is based on the correlation of X-ray, optical and radio positions for sources detected in ROSAT (S_0.08-2.4keV_>6x10^-15^erg/s/cm^2^, 69 sources) and ATCA (S_1.42GHz_>250uJy, 93 sources) observations of the Einstein Pavo field. A total of six ATCA radio sources inside the inner ring of the ROSAT image are located within 10" of the ROSAT X-ray positions, with one associated by random chance.
