>The nature of alpha , BETA , gamma radiation and the influence on organic polymers from the viewpoint of textile technology are discussed. Phenomena, such as splitting of the chemical bond, radical formation case effect , recombination, and interlacing are described. A summary is given of the properties of those radioisotopes which are used predominantly in the textile industry, namely, C/sup 14/,Na/sup 22/,Na/sup 24/ , etc. Because of the great importance of gamma radiation for modifying fibers, and the use of Co/sup 60/ as the main source of this radiation, the reaction of the most significant polymeric group to this radiation is shown in their structural formulas. The great influence of the environment (air, oxygen, nltrogen) on the course of the reaction is emphasized. The chemical and physical changes, which the most common textile fibers undergo under the impact of gamma radiation and neutron bombardment, are discussed, and graphs are given which show the relationship between radiation energy and physical parameters of cellulose (cotton), protein fibers (silk and wool), polyacrylates, polyesters, polyamides (nylon), and acetate fibers. In general, most fibers undergo deterioration in quality, while a minority show improvement of certain properties. (OID)
