Abstract: Various test surfaces and specimens were exposed on YAG-39 and YAG-40 to fallout from Shots Zuni, Contaminability-decontaminability Flathead and Tewa. (C-D) studies were conducted when the ships returned to Eniwetok Lagoon. Three days after Zuni the average reading in the nonwashdown area of the YAG-40 was approximately 350 mr/hr and in the washdown area approximately 90 mr/hr. When the decontamination studies were initiated, the average levels after Flathead were lower than those after Zuni by a factor of 10. The average nonwashdown reading was 35 mr/hr and the washdown reading, 10 mr/hr. The removal of the removable radiological protective coating (RRPC) after Zuni in the nonwashdown area removed all but 0.5 to 8.0% of the contaminant, while firehosing alone left a residual of 6 to 28%.

Estimates of fallout duration times and energy distribution of the dose from a plane source were made and the effect of diffuse source-geometry on the depth-dose to air-dose relationship was considered. Superficial doses from soft gamma and beta radiation were also considered.; Major Descriptors: *FALLOUT -- RADIATION HAZARDS; *FALLOUT -- RADIONUCLIDE MIGRATION; *HUMAN POPULATIONS -- RADIATION DOSES; *MARSHALL ISLANDS -RADIOACTIVITY; *RADIONUCLIDE MIGRATION -- RADIATION DOSES 900394| Country of Origin: United States Country of Publication: United States Abstract: The physical factors and dosimetry of the fallout on the Marshall Islands from the first shot of Operation CASTLE are discussed. Data was summarized from field Radiological Safety surveys, fallout radiochemical studies, and fallout gamma spectral measurements. The
