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 8 hours after they were fed with the Bikini ash (fission products) (fables 6 and 7 respectively). It is thus found that, though mst part passes by the digestive organs, some part is absorbed and deposits selectively in the bone, thyroid, kidney, and liver (Table 8). When 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). ina As to the patients, the radioactivity of the urine (15 cc) collected - tube at the early dates was measured and the number of counts was found to be several times the background counting. The same result is obtained for the concentrated urine. These are the evidences for the deposit of the radioactivity in the patient's body. The radioactivity was also measured by a scintillation counter placed near the thyroid. In one case, the count was 8 times that of the background on March 26 (see Fig. ) and 2 times on April 13. From the half-life and the absorption curve of the X-ray, it is presumed that [131 deposited in the thyroid. Similar conclusion is arrived at for other patients, too. On the basis of the fundamental observation described above, we shall discuss the clinical symptoms. It is convenient to cite the following statement published on April 1) by the clinical subcommittee of the Council for the Investigation of the Atomic Bomb Sickness of the Department of Public Welfare in the names of Yoshio » the Director of Tokyo University Hospital, and Shigenobu Kuriyama, the Vice Director of the First State Hospital of Tokyos "On March 28, five of the patients of Bikini accident entered the Tokyo University Hospital (seven in all because two patients had been there already) and 16 patients entered the First State Hospital of Tokyo. Though the degree of injury varied from person to person, all of them were found to be the patients of the acute radiation sickness due to the radioactive ashes, "The radioactivity inside and outside of the body was considerably high at the time of their entrance to the hospitals. decreased later on by an appropriate treatment. -k yeh - ot Tea , ie s te: Bes : : - But it The content of : » a >
