192 Health Physics our best estimates of internal dose varied less than two-fold withm the southern atolls and within the midlatitude atolls, suggestmg that the doses within each of those groupsofatolls were relatively consistent Uncertamty m estimated doses has been assessed based on some simplifications, and while uncertamties are relatively large, as expected, our estrmates of intakes of fallout radionuchdes by the Marshallese, and their related doses, contam no known biases that require correction or that might unduly fluence the estimates of cancer risk provided by Land et al (2010) Our estimates of radiation dose to the Marshallese livmg onall mhabited atolls should add considerably to our understanding of the cancer risks to the Marshallese from nuclear testmg at Bikini and Enewetak durmg the years 1946-1958 In addition, these estimates of intakes and related doses add to our understandmg m more general ways about the consequences of exposure to radioactive fallout from nuclear detonations Acknowledgments—This work was supported by the Intra-Agency Agree mentbetween the NabonalInsbtute of Allergy and Infectious Diseases and the National Cancer Institute, NTATD agreement #¥2 Al $077 and NCT agreement #¥3-CO S117 ‘Theauthors are mdebted to several mdividuals whose analyses and research have made substantial contnbubons to this work They mclude Payne Hams, who collected and analyzed the origmal urme samples of the exposed Marshallese, Wilham Robison for vanous data and publications ‘on radionuclide measurements made m the Marshall Islands, Shawki Ibrahim for analysis of f, data on fallout radionuchdes, Brian Moroz for meteorological analysis and graphic support, Jack Robbins (deceased) for discussions about thyroid exposures and bssue damage seen amongthe Marshallese, as well as other scientists who have added to our understand ing ofthe contarmmation and consequences 1m the Marshall Islands through ther scienbfic publications, many of which are cited here REFERENCES Apostoae: AI, Miller LF Uncertainties in dose coefficients from ingestion of "1, "Cs, and Sr Health Phys 86 460482, 2004 Beck HL, Bouville A, Moroz BE, Simon SL Fallout deposition in the Marshall Islands from Bikim and Enewetak nuclear weapons tests Health Phys 99 124-142, 2010 Bertelh L, Melo DR, Lipsztein J, Cruz Suarez R AIDE internal dosimetry software Radiat Protect Dosim 130 358367, 2008 Bevington PR Data reduction and error analysis for the physical sciences New York McGraw Mill, 1969 Bouville A, Beck HL, Simon SL Doses from external irradi anon to Marshall Islanders from nuclear weaponstesting Health Phys 99 143-156, 2010 Chilean Todine Educational Bureau Todine content of foods London Lange, Maxwell & Springer, 1952 Comroe JH Physiology of perspiraton Chicago Year Book Metical Publishers, 1965 Cronkite EP, Conard RA, Bond VP.
