UNCLASSIFIED t/ . ACTION: This offer was made on March 2h. On March 26 we obtained urine from two patients, On April 1 we cbtained urine from 5 more. We have not obtained urine from the remaining 16 patients despite our repeated attempts to do so. (2) I offered tu scan the fishermen for radiation, using twu Seinti- 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, information to Dr. Kobayoshi on fpril 7. I transmitted this (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. Except for the small amount of ash turned vver to me by Dr. Nakaizumi end a similar amount which I recovered on a subsequent visit to the Fukuryu Meru, no ash has been made available tO use (5) In response to Japanese requests, I agreed to recommend monitoring procedures for the tuna inspectors. ACTION: Monitoring procedures was devised but I deferred the question ef maximum permissable contamination until more information became available on the extent and type of contamination. I agreed to stand by until the first contaminated tune were found by inspection, at which time I would go to the scene of inspection and recommend specifically on the basis of my own observations whether the catch should be accepted or rejected. As noted elsewhere in some detail, the Japanese never permitted me to examine tuna which was alledgely contaminated. SPECIAL PROBLEMS ARISING OUT OF THE INCIDENT The mishap to the Fukuryu Maru created a number of separate, but inter- related 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 separately. Other problems which required attention were: Ln. r - 5 ‘ .. Lh ? aa, é “eo Z UNCLASSIFIED
