I briefly report on the X-ray detection of 10 radio sub-mJy sources in the 2Ms Chandra observation of the Hubble Deep Field North region. These sourcesfollow the same radio/X-ray luminosities relation which holds for nearbygalaxies. Making use of this relation, X-ray number counts from star forminggalaxies are predicted from the deep radio Log N-Log S's.Comment: 1 page, 2 figures.
