The tails of small angle X-ray scattering curves of polyethylene irradiated with different dos age have been analysed and found to agree with Porod's linearity relations of two-phase model. After irradiation the two-phase demarcation of polyethylene remains unchanged. The correlation length estimated from integral invariant and the intercept of a straight line does not change with dose remarkably. These results agree with the prediction of 'lamellar core damage mechanism' and do not coincide with the prediction of 'lamellar surface damage mechanism'.
