Cobalt 60 was not detected in the control
The average ratio between 13765 and 604 body burdens in the ex-
posed copulation was 490.
The 1370, to 8066 activity ratio was assumed to be
of the same magnitude for the control population.
bedy burden was estimated to be well below the MDL,
Because the baseline 6005
it was assumed to be .2% of
the control group body activity for 1370, in the determination of the long term
biological remove rate constant.
Tables 1 through 4 present the January and May 1979 13765 body burdens,
‘elapsed time and long term biological removal rate constants as measured in
Marshallese adult males, adult females, adolescents and juveniles.
Data pre-
sented in these tables are for individuals whose body burdens in January and May
are significantly above the baseline 1376, body burden for the control
population.
A body burden was included in the data set if it exceeded the mean
13765 body burden of the control population plus three standard deviations of
the mean.
Table 5 presents similar data for 6960.
Because 6065 was not detected in
the control population, no acceptance criteria were applied to the body burden
in this table other than the quantitative presence of two consecutively
decreasing 600, bedy burdens.
RESULTS
Table 6 summarizes the individual data presented in Tables 1 through 4 for
13765 and compares the data with values listed in ICRP publication 10 (ICaP6s)
and NCRP report 52 (NCRP77).
The biological removal rate constants for adult
male and adult female Marshallese are in agreement with previously reported
data.
The biological removal rate constant for adolescent Marshallese is
similar to the value reported in NCAP report 52 (NCRP77) for juveniles.
