Management Controls Fiscal control will be exercised in the form of monthly comparisons, over the task term, of accual 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 in conformance with generally acceoted standards for R&D and other investigative or analytic procedures, as observed by universities and large independent research facilities including Brookhaven National Laboratory (BNL). aOf. Technical Progress. Technical Progress in BY-3 (FY 1979), A preliminary literature search and consultations with Dr. C.aA. Sondhaus, University of California, have been completed. This has resulted in defining areas of uncertainty in information available and establishing the procedural steps that shouid be carried out to reassess the dose estimates. All available data on external radiation measurements, radionuclide concentrations in soil, water, vegetation, animal and food items have been collated. Historic samples collected from Rongelap and Utirik have been submitted for 129 analysis. Pertinent meceorological data pertaining to the BRAVO test has been researched and the information supplied to Lawrence Livermore Laboratory so that they can go ahead with the com puter simulation of fallout transportation and deposition. ‘ thor Oe nasca Q* Cr The !29r detarminations of the soil samples have been completed for those ic samples chat were available.
