We present an analysis of X-ray absorption in the nearby starburst galaxy M82. The X-ray attenuating column densities in the northern part of the M 82 outflow can be associated with cold disk gas detected in maps of H1 and CO (1→0). We derive an XCO factor which is somewhat lower as compared to that in our Galaxy. This is in good agreement with multi-transition line studies of various molecules in the disk of M 82.
