Title: The feasibility of using {sup 129}I to reconstruct {sup 131}I desposition from the Chernobyl reactor accident

Radioiodine released to the atmosphere from the accident at the Chernobyl nuclear power station in the spring of 1986 resulted in large-scale thyroid-gland exposure of populations in Ukraine, Belarus, and Russia. Because of the short half life of {sup 131}I (8.04 d), adequate data on the intensities and patterns of iodine deposition were not collected, especially in the regions where the incidence of childhood-thyroid cancer is now increasing. Results are presented from a feasibility study that show that accelerator-mass-spectrometry measurements of {sup 129}I (half life 16 {times} 10{sup 6}y) in soil can be used to reconstruct {sup 131}I-deposition density and thus help in the thyroid-dosimetry effort that is now urgently needed to support epidemiologic studies of childhood-thyroid cancer in the affected regions. 32refs., 9 figs., 3 tabs.
