SUMMARY

The hematological changes of Japanese fishermen exposed to fallout in
1954 were reported with other findings.
Generally speaking,it is difficult to estimate correctly the exposed radiation

to decide the therapy which should be given to heavily irradiated subjects.
As to the Japanese fishermen, it seems to be very important as well as
necessary to detect the significance of subtle changes such as they arestill
observed in hematological and cytogenetical examinations.
