The medical charts were of 50 subjects exposed to 175 rad at Rongelap Island, 12 exposed to 69 rad at adjacent Ailinginae Island, and 4 exposed in utero. According to the medical charts, all except those exposed in utero complained of the same acute symptoms as those experienced by the survivors of Hiroshima and Nagasaki immediately after exposure, such as radiation burns, decreased blood count, nausea and epilation due to radioactive fall-out. Among those exposed to 175 rad, 19 under age 10 and all 10 over age 31 had burns and all 10 between ages 21] and 30 had decreased blood count (see table). Subsequently, spontaneous abor- tions, stillbirths and hematemesis have been occurring repeatedly, and recently visual disorders, cataract and "aging phenomena" have become marked. £ note is the fact that differing from Hiroshima and Nagasaki more than a half of them have developed thyroid disorders including cancer. This is due to the large intake of radioactive iodine after irradiation through drinking water, etc. It was learned that 13 of the 19 exposed to 175 rad had all or part of their thyroid gland removed by the Americans and were making up for the loss of thyroid function by taking hormones regularly. Besides,'5 of the 20 persons who have died so far were cases of leukemia and cancer of the genital organs. The professors of the Atomic Disease Institute, Nagasaki University School of Medicine who have seen the charts, and the physicians of the Red Cross Nagasaki A-bomb Hospital who have administered medical care to the 2 islanders, say, “Development of cancer and leukemia can be expected to continue in future." However, according to the islanders the present situation is that no specialist is permanently stationed on the island and they have to get by with health examination and administration of medicine about once a year. (Note) "Rad" is a unit of measurement of absorbed radiation dose. It ‘is said that exposure to over 100 rad in a short space of time will cause death or such diseases as cancer and that when exposed to over 800 rad all will die. US to Make Full-scale Study on Residual Radiation Soon According to Micronesian Assembly sources, the United States Government will conduct shortly a full scale residual radiation survey on the Bikini Atoll and surrounding islands of the Marshall Islands which had been the nuclear testing ground of the United States from 1946 to 1958. The US Government had proclaimed 8 years ago that the residual radiation on the Bikini Atoll was "safe." However, voices requesting a full-scale reinvestiqation heightened subsequently among the still worried former residents of the Bikini Atoll, and the matter had developed to the point where a lawsuit was instituted against the US Government at the Hawaiian Regional Court of Law in October last year. This is a case where the US Government was pressured into taking action by the islanders' power. The expense will be 1.5 million dollars (about 459 million yen). Revortedly, it is the wish of the US Government to complete all studies by the beginning of next year at the latest.. 7 .
