The fully samples Columbia 1/sup 0/ CO survey and the Berkeley H I survey are compared with the COS B gamma-ray survey. As a first step, the study is limited to the high-energy gamma-rays (Eapprox.300 MeV). It is found that a simple model, in which uniformly distributed cosmic rays interact with the interstellar gas, as traced by H I and CO, can account for almost all the observed gamma-rays. Furthermore, if the contribution from point sources to the gamma-ray flux is significant, these sources must have a galactic distribution similar to that of CO. The analysis permits calibration of the ratio between H/sub 2/ column density and integrated CO line intensity: N(H/sub 2/)/W/sub CO/ = (1-3) 10/sup 2/0 molecules cm/sup -2/ K/sup -1/ km/sup -1/ s.
