This study deals with the shape and kinetic changes of the ESR spectra of eight irradiated starchs, from several hours to several months after ..gamma..-irradiation. Whatever the origin and water content of the starches two major radicals or groups of radicals are observed. The kinetic law depends on the water content; two main zones are pointed out which are relative to the amorphous and crystalline parts of starches.
