Change of the hydrogen concentration induced by ion irradiation in the polyethylene films has been studied by MeV proton backscattering. Ion implantation of polyethylene film results in a strong breakup of chemical bonds in the chains with a large hydrogen emission leaving a carbon enriched film. These effects are confined in a cylinder around the ion track, of cross section 10[sup -5] cm² and a length comparable with the ion range.
