LEVEL TEXT Following the detonation on Bikini Atoll on March 950. ABSTRACT 1, 1954, 28 Americans and 239 Marshallese were exposed to fallout. The radiation dosages received by the individuals ranged from 14--175 r. Some immediate ' 801. Item KEYWORD(S) effects observed were mild nausea, burning of the eyes, and itching of the skin. Later, signs of radiation injury included epilation and the development of spotty, superficial, hyperpigmented skin lesions that desquamated from the center of the lesions outward. All lesions healed rapidly with no further breakdown of the skin noted during the observation period. In those individuals in which hematologic changes were definite, lymphopenia appeared promptly and persisted for a prolonged period of time. The most consistent hematologic change was the depression in the platelet counts. Urinary excretion of radioisotopes was studied. From this it was determined that ingestion and inhalation of isotopes did not contribute significantly to the initial radiation exposure.

ABSTRACT Pressure-time vs. distance measurements were made on Mike and King Bursts of Operation Ivy. Mike Burst offered an opportunity to verify experimentally the applicability of the W{sup 1/3} scaling law at large yields; and on King Burst it was possible to observe the development of the shock waveform over land and over water. The scaling law was found to be valid for yields as large as the Mike yield. Overpressures from Mike Burst are in agreement with the assumption “that the pressures to be expected from a yield, W, burst at the surface of a perfect reflector, are the same as would be observed from a yield of 2W, burst in free air. Measurements on King Burst showed that the waveform over water was nearly ideal, whereas that over land was subject to deterioration as a result of the thermal and 5003426 OFFICIAL USE ONLY
