Nuclear Weapons: Devastation Inside the US

Christopher Nolan's film Oppenheimer has focused new attention on the legacies of the Manhattan Project — the World War II program to develop nuclear weapons.

As the anniversaries of the bombings of Hiroshima and Nagasaki on Aug. 6 and Aug. 9, 1945, approach, it's a timely moment to look further at dilemmas wrought by the creation of the atomic bomb.

The Manhattan Project spawned a trinity of interconnected legacies. It initiated a global arms race that threatens the survival of humanity and the planet as we know it. It also led to widespread public health and environmental damage from nuclear weapons production and testing. And it generated a culture of governmental secrecy with troubling political consequences.

As a researcher examining communication in science, technology, energy and environmental contexts, I've studied these legacies of nuclear weapons production. From 2000 to 2005, I also served on a citizen advisory board that provides input to federal and state officials on a massive environmental cleanup program at the Hanford nuclear site in Washington state that continues today.

Hanford is less well known than Los Alamos, New Mexico, where scientists designed the first atomic weapons, but it was also crucial to the Manhattan Project. There, an enormous, secret industrial facility produced the plutonium fuel for the Trinity test on July 16, 1945, and the bomb that incinerated Nagasaki a few weeks later.

(The Hiroshima bomb was fueled by uranium produced in Oak Ridge, Tennessee, at another of the principal Manhattan Project sites.)

Later, workers at Hanford made most of the plutonium used in the U.S. nuclear arsenal throughout the Cold War. In the process, Hanford became one of the most contaminated places on Earth (for more see video below). Total cleanup costs are projected to reach up to $640 billion, and the job won't be completed for decades, if ever.

Victims of Nuclear Tests

Nuclear weapons production and testing have harmed public health and the environment in multiple ways. For example, a new study released in preprint form in July while awaiting scientific peer review finds that fallout from the Trinity nuclear test reached 46 U.S. states and parts of Canada and Mexico.

Dozens of families who lived near the site – many of them Hispanic or Indigenous – were unknowingly exposed to radioactive contamination. So far, they have not been included in the federal program to compensate uranium miners and "downwinders" who developed radiation-linked illnesses after exposure to later atmospheric nuclear tests.

On July 27, however, the U.S. Senate voted to extend the Radiation Exposure Compensation Act and expand it to communities near the Trinity test site in New Mexico. A companion bill is under consideration in the House of Representatives.

The largest above-ground U.S. tests, along with tests conducted underwater, took place in the Pacific islands. Meanwhile, the Soviet Union and other nations conducted their own testing programs. Globally through 2017, nuclear-armed nations exploded 528 weapons above ground or underwater, and an additional 1,528 underground.

Estimating how many people have suffered health effects from these tests is notoriously difficult. So is accounting for disruptions to communities that were displaced by these experiments.

Polluted Soil & Water

Nuclear weapons production has also exposed many people, communities and ecosystems to radiological and toxic chemical pollution. Here, Hanford offers troubling lessons.
