Utetary and living pattern information will be derived from direct observations of island residents, and from standardized interviews with tsland residents
curing programmacic field trios.
Managemenc Controls
Fiscal control will be exercised in the form of monthly comparisons, over the
cask term, of actual cosets incurred against corresponding line items of the budgec.
Tecnnical results shall be monitored through a periodic review, by the Contractor
Task “Manager, of accomplishments by measuring actual performance as compared to exgected progress.
All work shall be conducted in conformance with generally accepted standards for 8&) and other investigative or analytic procedures, as observed Dv universities and large independent researcn facilities including
Srookhaven Nacional Laboratory (BNL).

Teecnnical Progress.
Technical Progress in 3Y-3 (FY 1979),
External and internal dose equivalents received during residency on 3ikini
island and internal dose equivalents to be received post residency were evaluated
for former Bikini residencs.
Bioassay results from samples collected in January
and Mav 1979 and prior bioassay results were used to construcc individual
7Ug7-90y body burden hiscories.
Whole body counting results during 1979 and
results obtained in prior years were used to establish l3/cg + 137Og2 individual body burden histories.
Daily activity ingestion rates were calculated
from the body burden data.
Uptake regimes which bese fit the activity tngesction
cate data were; constanct continuous uptake for 90S¢ and stepwise {ncreasing uposake for 137cs,.
Dosimetric models which described the uptake scenario were detived and individual dosimetric resulcs for persons residing on Bikini Island somecime during the years 1969 and 1978 were determined.
In addition, doses due co
residual radioactivity in persons after departure from Bixini were calculated.
[n-
iividual body burdens, urine activity concentrations and dose equivalents have been
recorded or stored in a computer data base.
Publicacions and reports describing
sasimetric methods and results, whole body counting results and biological removal
rate constants for Bikinians have been written.
Roucine personnel monitoring was provided for Aongelap and Utirik residents.
A statistical analysis was performed to decermine the minimum sample size needed to
establish che mean !3’c¢ body burden ac the 90% confidence level,
Male and fe-
male adult, adolescent and child categories were counted at each atoll and many
.ersons who participated in prior whole body counting visits were recounted.
[n
addiction, urine bicassay samples were collected from adult and adolescent populacion groups.
Body burden histories and dosimetric results have been completed for
nalf the residane populations for’ years following rehabicacion of che arolls.
