RESULTS
Persons listed in Tables 9 through i2 have been identified as medically
registered residents.
This terminology means these individuals reported to 3NL
doctors for sick call during the April 1978 field survey and were assigned a registration number.
For continuity,
these numbers were retained by SEP for
radiochemical analysis of urine identification.
Individuals who donated urine
for analysis of 995, and 1370, in 1979 and did not report for sick call during
the April 1978 survey at Bikini Atoll have been termed non-medically registered.
Persons who had not resided at Bikini Atoil for more than three years as of
January 1979 or had never resided at Bikini Atoll are Labeled as comparisons.

There is a general increase in
1977 by a factor of 13.3,
and from 1977
The general increase for adult females from 1977 to
1978 was slightly higher than that for males over the same period.
In most
cases, the January 1979 data are significantly lower than the 1978 with an
averaged reduction in the

Cs body burden by a factor of 2.9.
The May 1979
and August 1980 data follow the expected decreasing trend.
Tables 11 and 12 summarize the 1376, body burden data collected for adolescents and children.

for height and weight differences between subjects and the standard, up to 15%
