mates at odds with other analyses for all atolls studied. The wind data needed for this approach are too sparse, leading to results that are not credible (Reference 22). INTERNAL DOSE The current Brookhaven report has a number of features that make it useful for comparison with internal dose estimates for the Rongerik servicemen: closely related urinalysis data for the Marshallese and the servicemen are utilized in similar internal dose methodologies; the latest thyroid dose estimates (to the Marshallese) exceed any of the referenced previous estimates; and use is made of ICRP-30 (Reference 14), a likely foundation for the present analysis had all of the metabolic and dosimetric information for specific radionuclides been published when this work wasinitiated. Both the Brookhaven and the present assessments utilize I-131 counts from urinalyses to arrive at initial body burdens of I-131. From this, Brookhaven determines the levels of other iodine isotopes that lead to thyroid dose. The present analysis goes beyond, with use of Reference 11, to determine the levels of radionuclides generally, and from them and References 16-18, the doses to all relevant organs. Thus, the central comparison is afforded by the specifications of iodine metabolism and how they influence the estimates of initial I-131 body burden. The common basis for the ORNL-TM-190 (Reference 16) and ICRP-30 (References 14, 15) treatments of iodine metabolism is Reference 23. TM-190 has applied the Reference 23 prescription numerically as a function of time for various body compartments; ICRP-30 gives approximated time constants for these compartments, from which the user can develop functional relationships. When this is done, the agreement between I-131 body burdens deduced from ICRP-30 and TM-190 is good, especially with the approximations taken into account. However, this agreement exists only-for the latest version of iodine metabolism expressed in ICRP-30, Part 3 (Reference 15). Unfortunately, Brookhaven referenced ICRP-30, Part! (Refer- ence 14) as its source of metabolic information, which has since been acknowledged as incorrectly stating the iodine parameters (References 15, 24). Whereas the difference has a minimal impact on the principal ICRP-30 mission of determining annual limit 29
