Bio-environmental Monitoring The bio-environmental program for Operation Dominic was under AEC contract with the University of Washington, Seattle, Washington. A final report of their data is found in "Radionuclide Content of Foodstuffs Collected at Christmas Island and at Other Islands of the Central Pacific During Operation Dominic, 1962", UWFL-87, by Ralph Palumbo. During the period April 7 to July 29, 1962, collections of foodstuffs (marine life included) were made from eight off-site islands and Christmas Island to ascertain the radionuclide content of the samples collected. In addition to samples collected by this group, USPHS off-site monitors furnished samples from areas not covered by the University of Washington scientists. Approximately 8,000 samples were collected during the time which covered pre-testing, testing and post-testing periods. Part of these samples were scanned promptly for radioactive content ,jhowever a majority of the samples were returned to the University of Washington for complete analysis. 58.
