Dear Mr. James Bradley,
Thank you for posting your request to History Hub!
The National Archives has a number of records relating to Operation Ivy and Task Force 132. Our Organization Authority File for Task Force 132 links the series Histories, 1952 - 1953. Some of the records in that series are still classified. Our Organization Authority File for Joint Task Force 132. Task Group 132.2 (Army Task Group), which included the 7131st Army Unit Signal Detachment, links the series Decimal Files, 1951 - 1952 and Histories, 1950 - 1952. Some of the Decimal Files are still classified, while the Histories do not have any access restrictions listed. For questions about access to these three series, contact National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
The National Archives Catalog also lists multiple additional authority files for components of Task Force 132, many of which have associated record series. Catalog searches for Operation Ivy also come up with a number of records. A Catalog search for Enewetak comes up with quite a few results as does a search for the alternate spelling of Eniwetok, although not all of these results are directly relevant to Operation Ivy. The Harry S. Truman Presidential Library & Museum has an Atomic Bomb Collection with materials related to nuclear weapons testing at Enewetak (spelled as Eniwetok in the finding aid) and may also have other documents concerning Task Force 132 and Operation Ivy. For access to these records, contact email@example.com. The Eisenhower Presidential Library & Museum has a finding aid listing material in their collections relating to nuclear testing, to include Operation Ivy. Some of the items listed on the finding aid are still restricted. For questions about access to these records, contact firstname.lastname@example.org.
In addition, we located a number of official histories and other reports relating to Operation Ivy that are available online. United States Nuclear Tests, July 1945 through September 1992, published by the U.S. Department of Energy, briefly lists information about Operation Ivy. The Defense Threat Reduction Agency has posted on their website a brief fact sheet for Operation Ivy, as well as a much longer report entitled OPERATION IVY: 1952. Also available is the report “Nuclear Test Personnel Review Program: Analysis of Radiation Exposure for Expedited Processing -- Operation IVY, Land-Based Personnel, November 2011" on pages 135-147 of this pdf. The latter two reports briefly mention the 7131st Army Unit Signal Detachment.
We hope you find this information helpful. Best of luck with your research!
