Tsuzuki: I should like to make some remarks on the radiation injuries of twenty-three Japanese fisherman, which occurred 4 years ago. The fishermen lived together for 2 weeks on a ‘small contaminated boat. After 4 weeks they showed leukopenia and myelophthisis; after 6 weeks, disturbance of liver function and jaundice; after 3 months hypo- or aspermia, etc. We have lost one case, as a result of severe hepatitis. Now, after 4 years, all surviving fisherman are feeling well and looking healthy. I cannot say now anything about the late effects of their radiation injury.
