.
a”
Extérfial and internal doses are reconstructed for the 28 American servicemen stationedon Rongerik
Atoll, Marshall Islands, who were exposed to fallout on 1-2 March 1954 from Shot Bravg of Operation
CASTLE. External doses are determined from limited radiation survey and film badgé information.
Internal dose commitments are derived from urinalysis data. The magnitude of the calculated activity
intake suggests the principal pathways.
Reconstructed film badge doses are approximately 40 rem, with adjustments from individual activity
scenarios, as available. Internal dose commitments to the thyroid and large intestine (nearly all firstyear dose) provide the only significant increments to the external dose. Total doses are approximately
230 rem to the thyrgif, {115 rem to the lower large intestine, 85 rem to the upper large intestine, and
about 40 to 50’r
l other organs.
