controls, although it was not extremely high (Kimura et al., 1956).
After 8'/. years and 10 years, '’Cs- and Sr content in the urine of the
fishermen revealed no significant increase. At the same time the results cf
whole body counting showed nosignificant difference between fishermen and
controls.
Thus, the external irradiation seemed to play an impotant role in early
effects.

each patient’s behavior on the boat. The dose to each person differed depending on his behavior and the position of his cabin.
The integrated dose to the thyroid from ‘I was inferred as about 20 to
120 rads from external countings of radioactivity in the thyroid region during
the 4 to 7 weeks after the initial exposure.
Significant amounts:of radioactivity were found in the urine samples
collected at about 4 weeks after the explosion. The radioactivity decreased
rapidly, namely at about 6 months post explosion the activity in the urine was
barely detectable.
Radiochemical analysis of several organs from the fatal case showed that
the radioactivity of these organs was clearly higher, when compared with the
