We report thick-target yields of {sup 126,128,130}I from the bombardment of natural Te targets with 15-, 30-, 45- and 50-MeV protons, together with the iodine production cross sections for 1.85- and 5.0-GeV protons. With these data, we have estimated the relative cosmic-ray induced production of {sup 126}Xe, {sup 128}Xe and {sup 13O}Xe in Te ores. These quantities affect the ratio of double-{beta} decay half-lives of {sup 13O}Te and {sup 128}Te. A revised correction of cosmic-ray induced xenon can change the half-life ratio by as much as 10%, from (3.52{plus_minus}0.11) {times} 10{sup {minus}4} to (3.88{plus_minus}0.14) {times} 10{sup {minus}4}.
