In my cases, I think, the hours. Therefore, the radiation dose fishermen was at first small and then rapidly increased. As the fisher- men began to clean up at about 12:00, the exposure rate decreased thereafter. They were irradiated continuously for 2 weeks with decreasing dose rates. Aside from this external irradiation, internal exposure may have had some effects. But the internal irradiation seeed to have only a slight effect on the acute hematological changes.
