Going Nuclear: From New Mexico to Colorado to Nevada June 13, 2012Posted by Lofty Ambitions in Science.

Today’s post is an extension of or at least directly related to our “In the Footsteps” series, in which we trace the nuclear history of the United States.
On this date in 1911, Luis W. Alvarez was born. He would go on to become a world-renowned physicist, eventually awarded the Nobel Prize in 1968 for his work in particle physics, resonance states, bubble chambers, and data analysis. Just before his work on nuclear weapons at Los Alamos, Alvarez, while based briefly at the University of Chicago, helped develop a plan for the first intelligence gathering and monitoring of nuclear development in other countries, at the time Germany.
Then, he became one among a host of scientists who worked at Los Alamos in New Mexico on the Manhattan Project. There, Alvarez worked on the first plutonium bomb, Fat Man, which was used on Nagasaki. In fact, he flew on The Great Artiste with the detection equipment he developed to measure the explosive power of the nuclear detonations over both Hiroshima and Nagasaki. After the war, he turned his attention to particle accelerators, the Zapruder film of the Kennedy assassination, and the cause of dinosaur extinction.
Last Tuesday, Anna headed over to the local Barnes & Noble to pick up the new book by a recent Lofty Ambitions guest blogger. Kristen Iversen’s Full Body Burden: Growing Up in the Nuclear Shadow of Rocky Flats made its debut on June 5, 2012, and as a Discover Great New Writers selection. The book has been chosen as a common reader for incoming students at Virginia Commonwealth University, and it’s getting great reviews. So Anna tucked it into her bag and headed off to Las Vegas to read it under the cabana.
What we like about Full Body Burden is the concept of science writing to which we keep returning here at Lofty Ambitions, namely that good science writing tells a story and is about the people as well as the science or technology. Kristen goes one step further, as we do here on our blog, by weaving her own story—memoir—into the larger cultural story. Or rather, Kristen recognizes that she too is part of the story of Rocky Flats in Colorado, where she spent her childhood and where plutonium triggers for nuclear weapons were produced until 1992. So we learn about Kristen’s horses—Tonka, Sassy, and the others—and family life in the 1960s and 1970s, as well as about the fires in 1957 and 1969 at the Rocky Flats facility operated then by Dow Chemical.
The story of Rocky Flats, including its two major fires and its day-to-day leakage, is one that most of us don’t know. To put its importance in perspective, here’s a tidbit from Full Body Burden: “In early December 1974, residents wake up to a socking headline in the Rocky Mountain News: cattle near rocky flats show high plutonium level. An Environmental Protection Agency (EPA) study has found that cattle in a pasture just east of Rocky Flats have more plutonium in their lungs than cattle grazing on land at the Nevada Test Site, where the United States conducted hundreds of aboveground nuclear explosions in the 1950s and 1960s. Plutonium, uranium, americium, tritium, and strontium are found in measurable quantities in the cows’ bodies, and levels of plutonium in the lungs and tracheo-bronchial lymph nodes of the cows are especially high.”
Indeed, 928 nuclear tests (some with multiple detonations) were conducted both above and below ground at the Nevada Test Site (check this link to see warning to users) between 1951 and 1992, the year the United States agreed to a nuclear test ban and the year Rocky Flats stopped producing plutonium triggers. While the United States performed more than 200 atmospheric tests, some of those were done in the Pacific Ocean. The vast majority of nuclear tests in Nevada—more than eight hundred—were underground detonations. The last aboveground test at the Nevada Test Site occurred on July 17, 1962. Of course, underground tests raised dust too, and some, like Buster-Jangle Uncle in 1951 and Baneberry in 1970, had visible releases of fallout well above the Earth’s surface.
We know these facts about the Nevada Test Site in part because, while in Las Vegas, we usually visit the Atomic Testing Museum on Flamingo Road, just a few minutes drive off The Strip. Doug drove out to Las Vegas on Saturday to spend the night and retrieve Anna and some friends. So this trip provided another opportunity to visit the museum on Sunday, in the midst of reading about the nation’s nuclear history in Full Body Burden.
In the films at the museum, we were reminded of what the shift from aboveground testing to underground testing meant for the people involved in the program. One person pointed out that, though many scientists and engineers initially opposed the move, “The data was much better underground.” Another man, though, worries that, when we moved nuclear testing underground and out of sight, “We shielded ourselves and the public from what a nuclear test is really like.” The United States hasn’t conducted a critical nuclear explosion in twenty years.
The Nevada Test Site remains ready to resume nuclear testing, though. A test site engineer in one of the museum’s films went so far as to state, “As long as you have a nuclear stockpile, the day will come when you have to have a nuclear test.” A New York Times article this year notes that our current agreement with Russia limits us to 1550 deployed weapons and “thousands more warheads [that] can be kept in storage as a backup force” and additional short-range nuclear weapons. Given the order for a nuclear test, the Nevada Test Site could be ready again within two or three years.
