Fallout from Shots BRAVO and ROMEO was the major source of contamination on most of the ships and islands. Varying amounts of fallout from Shots UNION, YANKEE, and NECTAR contributed somewhat to the total deses of the shipboard and island-based personnel; no fallout was experienced as a result of Shot KOON. Shipboard personnel received additional exposure from hulls and salt water piping systems that had become contaminated from operating in the radioactive waters of Bikini Lagoon. From the reconstructed radiation environments, both topside and below, an equivalent film Agreement is very good badge dose is calculated and compared to actual dosimetry data. When topside intensities during badged periods when the ships received significant fallout. 20 DISTRIBUTION / AVAILABILITY OF ABSTRACT CO UNCLASSIFIEDAUNLIMITED =) SAME AS RPT 22a.
