摘要：

The products obtained after gamma irradiation with doses 9.1, 18.2, 36.3, 54.5 kGy of native starch and water suspensions of starch were investigated using small-angle X-ray scattering (SAXS). Relations between changes in the scattering curves (diminution of the intensity of the reflection related to distance d is-approximately-equal-to 100 angstrom and elevation of scattering curves) connected with destruction of long-range ordering in starch granules, and the conditions of the irradiation process were observed. Irradiation influences the long-range ordering more intensively in cases of native starch as compared with water suspensions of starch irradiated.
