Country of Publication: United States Abstract: Results of a study of the hydrology and geochemistry of Enewetak Atoll are reported. Downhole probes were used to measure salinity, temperature and dissolved oxygen profiles in situ. Samples were pumped from various depths in the wells and/or dipped from the surface for radionuclide and chemical analysis. Rainfall was monitored and tidal * responses of the wells determined.

In the first report, a roentgenographic survey of the skeletal system was made on 74 children who were exposed in utero to the atomic bomb explosion in Nagasaki, Japan at distances under 2000 meters from the hypocenter. The findings were compared with those on a group of 91 children also exposed while in utero to the bomb but at distances of 4000 to 5000 meters. No differences in the incidence of skeletal abnormalities were found between the two groups. In the second report, a description of injuries suffered due to fallout after the explosion of a thermonuclear device on the Marshall Islands is presented. Marshallese and Americans were accidentally exposed on islands in this area, receiving whole-body and minimal internal contamination. The highest dose (an estimated 175 r) was received by a group of 64 Marshallese. The dose of radiation received proved to be sublethal. Though there was significant depression of hemopoiesis, no clinical signs or symptoms developed that could be attributed with certainty to this effect. Skin lesions and epilation developed in 30% of the group beginning about two weeks after the exposure. Minimal amounts of radioactive material were detected in the urine. The internal deposition was insufficient to contribute significantly to the (38849 gamma radiation, beta radiation injury to skin, acute reaction, and it is believed there is no long-term hazard. Examinations conducted one year after the exposure revealed these people to be in generally good health. Slight depression of lymphocytes © and platelets persisted. A few pigment aberrations and minimal atrophy remained at the site of the deeper skin lesions.; Major Descriptors: *A-BOMB SURVIVORS -- PRENATAL EXPOSURE; *SKELETON -DELAYED RADIATION EFFECTS; *HUMAN POPULATIONS -- RADIATION INJURIES; *MARSHALL ISLANDS -- FALLOUT Broader Terms: AGE GROUPS; ASIA; BIOLOGICAL EFFECTS; BIOLOGICAL MATERIALS;
