YES HEY’a radiation crapulence. The estimated dose of radiation the fishermen received during the following two weeks is about 200 r. It is therefore not amazing that the bone and other organs suffered considerable injuries. Next, we shall discuss the most important problem, namely, the deposit of the radioactivity in the body. The outline of this problem was given already when we referred to the chemical analysis of the ash. We shall therefore begin here with the survey of the animal experiments. The radioactive deposits in various organs of mice are measured 12 hours and 48 hours after they were fed with the Bikini ash (fission products)(fables 6 and 7 respectively). It is thus found that, though most part passes by the digestive organs, some part is absorbed and deposits selectively in the bone, thyroid, kidney, and liver (Table 8). Then the fission product is given to the mice by hypodermic injection, it is found to deposit in the bone, thyroid, kidney, and liver in the same way as above and excreted through the digestive organs and with the urine (Table 9). As to the patients, the radioactivity of the urine (15 cc) collected ina tube at the early dates was meaSured and the mumber of counts was found to be several times the beckground counting. The same result is obtained for the concentrated urine. These are the evidences deposit of the radioactivity in the patient's body. The radioactivity was also measured by a scintilletion counter pleced near the thyroid. In one case, the count was 8 tires that of the background on March 26 (see Fig. 4) and 2 times on tpril 13. Pron the helf-life end the absorption curve of the X-ray, it is presuced that 1131 depesited in the thyroid. Similar conclusion is arrived at for other patients, too. On the besis of the fundamental cbservetion described above, we shall discuss the clinical sjyrptoms. nia It is convenient to cite the follcvirg statement pup by the clinical subcommittee of the Council for the Inve dteric Bomb Sickness of the Department of Yoshio ) the Director of Toinec Uni é zr 3 Kuriyama, the Vice Director of tne First Sieve Eospitai of To} "On Merch 28, five of the patients of Bikini accident entered the Tokyo University Hospital (sever in all because iwo fatients had been there already) and 16 catients entered the First Siete Eospitel of Tokyo.
