contain a large selection of fallout radionuclides as a result of 43 nuclear weapon tests conducted there between 1948 and 1958. The authors report elevated fallout radionuclide concentrations buried more deeply in the lagoon sediments and evidence of burrowing into the sediment by several species of callianassid ghost shrimp (Crustacea: The Thalassinidea) which has displaced highly radioactive sediment. burrowing activities of callianassids, which are ubiquitous on the lagoon floor, facilitate radionuclide redistribution and complicate the fallout radionuclide inventory of the lagoon.

Title: Analysis of radiation exposure for naval personnel at Operation GREENHOUSE. Technical report Corporate Source: Science Applications International Corp., McLean, VA (USA) Publication Date: 30 Jul 1982 p 130 Report Number(s): AD-A-151621/0/XAB; SAI-84/1062 Decument Type: Report Language: English Journal Announcement: ERA&505 Availability: NTIS, PC AO7/MF AOl. ERA (Energy Research Abstracts). Subfile: Country of Origin: United States Country of Publication: United States Abstract: The radiological environments are reconstructed for seven ships and the residence islands of Eniwetok Atoll that received fallout during operation GREENHOUSE (Aprili- May 1951) as a result of Shots BOG, EASY, and ITEM. From the reconstructed operations and radiological environments, equivalent personnel film-badge doses are calculated and compared with actual film-badge data available for six of the ships. Considering the increased time spent topside by badged personnel as opposed to an average crewmember, correlation between calculations and dosimetry is good. Average shipboard doses range from a low of 0.13 rem for the crew of the USNS LT. ROBERT CRAIG to a high of 1.14 rem for the crew of the USNS SGT. CHARLES E. MOWER. Average doses on the residence islands of Eniwetok Atoll range from 2.75 rem to 3.10 rem.
