We have compared our curves with
the curves of Yugoslavian accident
cases, and here again we found the
same difference, and our interpretation of these data was that probably
the difference between the irradiated
cases and the purposely irradiated
patients was that in the irradiated
patients the dose was very uniform,
with a maximum variation of plus or
minus 4 per cent, whereas in the case
of accidents the uniformity was much
less, and of the order of 30 per cent.

a type of uniform
And this irradiation
played an important role in the hema-
tological changes. The fallout material began to precipitate at 7:00 a.m.
and continued to fall for about 5
hours. Therefore, the radiation dose
to fishermen was at first smajl and
then rapidly increased. As thefishermen began to clean up at about 12: 00,
the exposure rate decreased thereafter.
They wereirradiated continuously for
2 weeks with decreasing dose rates.
Aside from this external irradiation,
internal exposure may have had some
effects. But the internal irradiation
seemed to have only a slight effect
on the acute hematological changes.
