Abstract:

The physical factors and dosimetry of the fall out on the Marshall Islands from the first shot of Operation CASTLE are discussed. Data was summarized from field Radiological Safety sur veys, fallout radiochemical studies, and fallout gamma spectral measurements. The influence of these and other factors on an evaluation of sur vey meter response and total dose estimates was considered. 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. Author
