THE IRRADIATION OF POVIDONE AND POVIDONE-IODINE A B S T RA C T Solutions of povidone are sterilized by gamma-irradiating the povidone in the presence of iodine and iodide ions. Preferably the gamma irradiation of povidone is effected in the presence of iodine with both iodide and iodate ions or as povidone-iodine in the presence of iodide and/or iodate ions. Sterilization is effected by gamma radiation as described above while preventing gelation of the povidone and degradation of the povidone-iodine.
