I repeated the assurances repeated carlier by Dr. “orton that we wished sincerely to be of assistance, that our participation was not motivated (as some Japanese suggested) by the opportunities for scientific studies, and that whatever data we ottained would be turned over to the Japanese investigators to be used by them in any way they saw fit. At this point it would be desirable to list the radiological studies which had been already made by the Japanese. These studies are of interest because they indicate the extent of Japanese capabilities in this field, and define the extent to which our facilities would be helpful to the Japanese. (1) Using a Cutie Pie, they measured the radioactivity of the Fukuryu Maru. These data appear completely satisfactory end prove to be in good agreement with measurements made with Anerican calibrated equipment. (2) They measured radioactivity of the fish and fishermen, using portable survey equipment. However, their equiprent vas not calibrated and their data were given in counts per minute as determined by the original factory calibration. (3) They determined that the ash recovered from the vessel was radioactive using an end window GM tube and scaler, aw Their counting system “as not calibrated and they reported counts per inate with no knowledge of the factor required to convert their data to standard units. (4) They completed a qualitative rediochenical analysis of the ash erd reported the following: Sr 89, Y91, Zr95, "No9Sm, Nb95, RulO3, Rulds, =h1l96, Sbl27, Tel32, 1131, 1132, B21h0, Lalyo, Celhl, cellh.

In vier of the importerce of this 2nalysis in evaluating the status of the patients, I urged that these samples be furnished imnediately erd assured them that in one week it would be possible to give then a report for the constituents of principal biological importance, I explained the need for cerial sa-ples and suzgested that collections be made at weekly intervals, Thsy sesred anxious to accept this service.
