Holmes and Narver mapped radiation exposure for humans and animals at AEC sites

By Roy Castellano · August 17, 2026

Residents of the Bikini and Enewetak Atolls were displaced and exposed to fallout in a project that now exists as a series of architectural drawings and repatriation plans.

Humans, plants, and animals were exposed to radiation in the name of national security, often without knowing the price they would pay. Some were moved from their ancestral homes in the Pacific, only to be tracked as biological data points in a contractor's file.

To keep a bomber fueled and a war plan viable, the United States had to master the physics of the blast. That mastery required more than just scientists in white coats; it required the heavy lifting of civil engineering. The US National Archives holds the record of that labor in the Project Files of Holmes and Narver. As a catalogue entry, the description outlines a vast repository of records generated by the Holmes & Narver Company, a firm contracted by the Atomic Energy Commission (AEC) to build the infrastructure for nuclear weapons testing and gas stimulation.

"Repatriation plans"

The catalogue entry records that these files include a grimly pragmatic assortment of documents: architectural drawings, maps, and reports. But beneath the technical specifications lie the human costs. The file's description explicitly lists "repatriation plans" and records of "fallout from nuclear weapons test shots," as well as "radiation exposure to humans, plants, and animals.

These were not localized incidents. The scope of the work spanned the globe, from the Enewetak and Bikini Atolls in the Pacific to the rugged terrain of Alaska and the high deserts of the Nevada Test Site. The records cover a dizzying array of operations that any former SAC officer recognizes as the building blocks of the American deterrent: Castle, Hardtack I and II, Ivy, Redwing, and Plumbob.

In the Pacific, repatriation was not merely a logistical hurdle; it was a moral one. When the catalogue mentions "repatriation plans," it refers to the attempt to return people to islands that had been used as laboratories for the most powerful weapons ever conceived. The infrastructure built by Holmes and Narver—the piers, the bunkers, the housing—was the physical manifestation of a policy that viewed geography as expendable if the result was a more credible threat to the Soviet Union.

1950 Fallout Controversy

When viewed alongside related archival series, the Holmes and Narver files become part of a larger, more unsettling pattern of AEC activity. The National Archives also catalogs "Central Subject Files" that document the "1950 fallout controversy" and a program known as "Project Sunshine." More disturbing still is the mention of a 1974 investigation into "plutonium injection experiments.

For those of us who spent years analyzing targeting cycles and war plans, the necessity of the testing program is self-evident. You cannot deter an enemy with a weapon you haven't proven. However, the related records suggest that the AEC's curiosity often outpaced its ethics. The transition from testing a weapon's yield to studying the "biomedical activities" of that weapon on human subjects marks the point where national defense slips into something far more opaque.

The Holmes and Narver files provide the structural context for these experiments. If the biomedical files record the effect of the radiation, the Holmes and Narver files record the sites where that radiation was unleashed. They are the blueprints for the theaters of exposure.

Operation Plowshare

The AEC's ambitions extended beyond the military. The catalogue entry mentions "gas stimulation" and a specific project called "Plowshare." This was the attempt to find "peaceful" uses for nuclear explosives—using the blast to carve harbors, create canals, or stimulate natural gas deposits. It was an era of nuclear optimism that viewed the atom as a tool for planetary engineering.

In Louisiana, Colorado, and New Mexico, the infrastructure for these experiments was laid down. The record includes "studies of seismic waves" and "safety plans," terms that sound reassuring in a catalogue but were often insufficient in practice. The hubris of the era suggested that we could control the fallout as easily as we could control the blast. The resulting records—the pamphlets, the memorandums, the graphs—are the remnants of a belief that the environment could be bent to the will of the state without permanent consequence.

The cost of the shield

The archive does not offer a narrative; it offers a list. It tells us that the files contain "correspondence, graphs, manuals, maps, memorandums, pamphlets, photographs, proposals, and reports." It does not tell us the names of the people who were exposed or the exact nature of the "repatriation" failures.

We are left with the knowledge that a private company, Holmes and Narver, was the architect of the spaces where the Cold War was physically contested. They built the stages upon which the AEC performed its most consequential and most questionable acts.

While the related series mention the investigation of plutonium injections and the controversy of fallout, the Holmes and Narver files remain the primary record of the hardware. The question that remains is how many of the "radiation exposure" reports mentioned in the catalogue were ever shared with the people being measured.
