ABSTRACT (Continue on reverse if necessary and identify by block number)

External and internal doses are reconstructed for the 28 American servicemen stationed on Rongerik

Atoll, Marshall Islands, who were exposed to fallout on 1-2 March 1954 from Shot Bravo of Operation

CASTLE. External doses are determined from limited radiation survey and film badge 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 first-

year dose) provide the only significant increments to the external dose. Total doses are approximately

230 rem to the thyroid, 115 rem to the lower large intestine, 85 rem to the upper large intestine, and
about 40 to 50 rem to all other organs.
