AbstractPolyethylene films were irradiated in various atmospheres by gamma‐rays from a Co60source, and solubility measurements against xylene were carried out at 80°C. In NO2and O2, the crosslinking of polyethylene is depressed markedly but in NH3, Cl2, and SO2not so much. On the other hand, N2O accelerates the crosslinking appreciably. In CO and H2, neither the depressive nor the accelerating effect is observed within a limit of error. In O2, the depressive effect is more considerable at higher gas pressure and at lower dose rate; however, in N2O the accelerating effect is reduced at higher gas pressure, and shows dose‐rate independence within the range of our experim
