of the damages. burns as a result of the thermal radiation; injuries as a result of the pressure wave; injuries as a result of the initial radiation; course of the first, second, and third stages of the radiation sickness; clinical symptoms of radiation sickness- hematology of radiation sickness. therapeutic measures of the Japanese doctors; and pathological anatomy of the atomic bomb injuries. Ascertainable injuries among the populafion years later include organic injuries and functional disorders, leukemia’ and carcinoma formation, development disturbances and illnesses of irradiated children inclusive of the in utero exposed, and genetic problems. Results of the Bikini fall-out are also described. Topics discussed include’ the radioactive fall-out, its distribution, and the radiation originating from it; the clinical and pathologicalanatomical state of the Bikini fishermen and the inhabitants of the Marshall Islands; radiation injuries as a result of the deposition of fission products on the skin and in the body; and results of additional investigations on the Marshall Island population 3 and 4 years after the rain of ashes.

Scripps Institution of Oceanography, J. Geophys. Research v 66. Publication Date: Nov. 1961 Journal Announcement: NSA16_ IN THE SEA PRODUCED BY NUCLEAR La Jolla, Calif. 3845-62 p. Document Type: Journal Article Language: English Low-frequency dispersive gravity waves produced by nuclear explosions at Bikini, Marshall lslands, were recorded at four distant island stations. The results of these wave measurements are compared with those predicted by linear theory, and good agreement is observed in the nature of the dispersion and the rate of amplitude decay with distance. The wave system associated with the large tsunami of March 9, 1957 is also considered. The dispersion for both types of disturbances was virtually identical, in agreement with the theoretical argument that the disper sion of a centered wave system is independent of the nature of the source disturbance. In analyzing the rate of amplitude decay, it was found necessary to correct the observations for enhancement due to scattering by the islands upon which the recording stations were located, showing that even relatively small islands are effective as scatterers. These experiments show rather conclusively that tide-gage records of tsunami-like disturbances are grossly misleading insofar as the characteristics of the wave systems in the open sea are concerned.

Journal Announcement: NSA16 Document Type: Journal Article Language: English Crater measurements from two near-surface nuclear explosions detonated at Bikini atoll in 1954 are tabulated. On the basis of the crater data from nuclear detonations, an extrapolation procedure was developed by which crater diameters can be predicted. This procedure is based on an empirical determination of the scaling exponent, m, as a function of soil type, using R = CW/sup 1/m, where R is radius, C is a constant related to the soil
