Natural production rates of the 16 million-year I/sup 129/ from spontaneous fission and cosmic-ray reactions are estimated to contribute a steady- state concentration of more than 10/sup -14/ gram of I/sup 129/ per gram of 1/sup 127/ to the hydrosphere, atmosphere, and biosphere. The concentrations are expected to be detectable by neutron-activation analysis in natural materials that concentrate iodine. Substantial additional contributions were made by fission-produced I/sup 129/ in fallout, serving as an intrinsic tracer for natural iodine kinetics. I/sup 129/ activation analysis has advantages as a tracer technique. (auth)
