‘"T uptake, PBI conversion rate and
Triosorb tests were added. No abnormal

1)
Whole Body Counting
Gammaspectrometric analyses by whole
body counting on the 13 exposed people
indicated no significant increase of '’Cs. No
difference was recognized between the curves
from the exposed persons and those from
the controls.
2) Radiochemical Analyses of Urine
'7Cs analyses were carried out on 24-hour
urine samples from 10 exposed people and
14 normal persons. The '’Cs content of
pCi/24 hrs. urine. On the other hand, the
"Cs content from normal urine samples was
distributed between 57.841.7 and 191.1426
pCi/24 hrs. and the mean '*’Cs contents were
112 pCi/24 hrs.
Considering the results of whole body
counting and urine analyses, '’Cs content of
the exposed people is not different from that
of the present normal Japanese.
b. "Sr+"Y¥
**Sr analyses were done on the pooled urine
samples collected from 3-5 exposed persons.
As the control, 3 normal samples were analysed. No significant increase was found on
the samples from the exposed persons.
