TITLE BUDGET AND REPORTING CODE Dose Reassessment for Rongelap HATO 2-01 -01-0 and Uticik CONTRACTOR NAME Associated Universities, Inc. cJe. / COOE BNL | WP NUMBER I DATE PREPARED | | 03/31/80 TASK NO. REV. NO. | 0 Approacn. The study will comprise: a. Literature search for all available data concerning the BRAVO test, such as, meteorological conditions and radiation measurements. Discussions with scitentific and technical personnel involved in the BRAVO cesc. 6b. Use of historic samples and teeth samples to determine lo IT, 90s, , and “39, 240pu concentracions to derive concencrations of other radionucidies. -m addition, excised thyroid glands from exposed Marshallese will be analyzed for 1297 and 99T¢ and data so generated will be used to estimate the concentrations of short lived todine isotopes. c. Diet and Life style studies to provide informacion for dose assessment. d. Computer simulation of the BRAVO cest fallout to deternine the transport and deposition of radtonuclides. Management Concrols Fiscal control will be exercised in the form of monchly comparisons, over che cask term, of actual costs incurred against corresponding line items of the budget. Technical results shall be monitored through a periodic review, by che Contractor Task Manager, of accomplishments by measuring actual performance as compared to expected progress. All work shall be conducted tn conformance with generally acm ceoted standards for R&D and other investigative or analytic procedures, as observed by universities and large independent research facilities including Brookhaven National Laboratory (BNL). Of. Technical Progress. Technical Progress in BY-3 (FY 1979), A preliminary literature search and consultations with Dr. C.A. Sondhaus, University of California, have been completed. This has resulted in defining areas * a Aw re of uncertainty in information available and establishing the procedural steps thac should be carried out co reassess the dose estimates. All available data on external radiacion measurements, radionuclide concentrations in soil, water, vegetation, animal and food {tems have been collated. Historic samples collected from Rongelap and Utirix have been submitted for L29y analysis. Pertinent meceorological data pertaining to the BRAVO test has been researched and the informacion supplied to Lawrence Livermore Laboratory so thac they can go ahead with the comouter simulacton of fallout cransportacion and deposition. The !29r determinations of che soil samples have been compleced for those samples chat were available. Some of these samples will also be analyzed Te, Ln addition, we are exploring the possibility of analyzing “Bikini- ie cori 39
