ABSTRACT:
A blood dialyzer having semipermeable polymeric dialyzing membranes is sterilized by impregnating the dialyzing membranes, for example, dialyzing hollow fibers, with an aqueous solution of a .gamma.-ray-absorbent and water-soluble dihydric aliphatic alcohol and irradiating .gamma.-rays to the dialyzing membranes, to prevent the deterioration of the dialyzing membranes and the generation of ultraviolet-ray-absorbent substance in the dialyzing membrane.
