Country of Origin: United States GRA eae Vw wtay (NTIS NTS) Country of Publication: United States Abstract: The atomic bomb detonation at Bikini during Operation Crossroads offered the opportunity for exposing various biological materials including corn seed to ionizing radiation. This experiment with corn was designed to determine the effects of radiation from the atomic bomb in causing (1) alterations of the chromosome mechanism of heredity; (2) direct injurious action on the plants grown from the treated seed; and (3) sterility due to chromosomal derangement and other causes. For purposes of comparison, duplicate samples of seed were exposed to measured dosages of x rays ranging from 5000 r to 25,000 r units.

JMT (DOE contractor) Country of Origin: United States Abstract: Serum and red cells from 20 Marshallese on two atolls and from 10 subjects in New York were compared for their elemental composition employing an energy dispersive X-ray fluorescence technique. The elements analyzed in serum included Cl, Zn, and Br, whereas red cells were analyzed for Cl, K, Fe, Zn, Br, and Rb. Both Marshallese groups showed statistically significant elevations in serum Br (51 and 96%) and in red cell Br (393 and 478%) as compared to the New York group. The Marshallese Br/Cl ratio in serum and in red cells was elevated when compared to that of the New York group, whereas the Rb/K ratios were equivalent. The red cell Br/serum Br ratio was also elevated in the Marshallese subjects. There were no similar differences noted among the other elements tested. Drinking liquids in the Marshall Islands were snalyzed for Br but did not provide a clear source for the elevated Br evels.
