_ ACTION: This offer was made on March 24, On March 26 we obtained urine from two patients, On April 1 we cbtained urine from more. We have not obtained urine from the remaining 16 patients despite our re- peated attempts to do so, (2) I offered tu scan the fishermen for radiation, using twu Scinti- meters that I had available, : ACTION: I have been unable to do this because they have not permitted the American team to have access to the patients. (3) In response tu the Japanese request I offered to provide a report on the biologically significant radio~isotopes present in the ash. ACTION: Dr. Nakaizumi gave me a small amount of deck sweepings from the Fukuryu Maru. This I have sent to the Health and Safety Laboratory for future study. The composition of the ash was actually known to the Commission from analysis performed by the Air Force on the material obtained from the Fukuryu Maru Prior te my visit. Authorization for transmission of this information to the Japanese was communicated to me in telegram No. 2199 from the Secretary of State to the Ambassador, I transmitted this information to Dr. Kobayoshi on April 7. . ~. (4) I offered to arrange for animal studies which would provide useful infurmation on absorption and metabolism of the various radiochemical components of the ash. ACTION: The Japanese reported the extent of the total amount of ash recovered as 50 millocuries, They now deny that this much is available and have no inventory of the material. Fxcept for the small amount of ash turned vver to me by Dr. Nakaizumi and a similar amount which I recovered on a subsequent visit to the Fukuryu Maru, no ash has been made available to US. (S) In response to Japanese requests, I agreed to recommend monitoring lassified procedures fur the tuna inspectors. , ACTION: Menitoring procedures was devised but I deferred the question of maximum permissable contamination until more information became available on the extent and type of contamination. I agreed to stand by until the first contaminated tuna were found by inspection, at which time I would go oto the scene of inspection and recommend specifically on the basis of my own gobservations whether the catch should be accepted or rejected. As noted 2 PS gelsewhere in some detail, the Japanese never permitted me to examine tuna wWhich was alledgely contaminated. 6 9 a Q > SPECIAL PROBLEMS ARISING OUT OF THE INCIDENT # = oe $ The mishap to the Fukuryu Maru created a number of separate, but interrelated problems. Of these, the most urgent was the clinical status of the 23 fishermen, a subject with which Dr. Morton is exclusively concerned and about which he will report separetely. Other problems which required attention were: ay 5 7 >
