Shifting Radioactivity Risks: A Case Study of Waste Management at the Fernald Nuclear Weapons Site
Since the late 1990s, the U.S. Department of Energy has produced several versions of “accelerated” cleanup schemes of its nuclear weapons sites. This has led to more rapid decommissioning of two large weapons plants – notably the Rocky Flats Plant in Colorado, where plutonium pits for nuclear weapons were mass produced, and the Fernald Plant near Cincinnati, Ohio, where uranium metal was produced, mainly for plutonium production reactors.

Brice Smith: The Environmental Transport of Radium and Plutonium
Radium is one of the principal contaminants associated with uranium mining and milling and affects a large number of sites. It also affects thousands of secondary oil recovery sites, where radium pollution is quite common. Plutonium is one of the most long-lived and dangerous radionuclides in the nuclear weapons production process.

Bad to the Bone: Maximum Contaminant Levels for Plutonium in Drinking Water
The promulgation in the United States of safe drinking water regulations for toxic chemicals and radionuclides in 1975 and 1976 pursuant to the Safe Drinking Water Act was a historic first step for making water safer for the public. But time has shown that many chemicals and radionuclides pose greater risks and a larger variety of risks to public health.

Nuclear Targeting: The First 60 Years
On May 5, 1943, the Military Policy Committee of the Manhattan Project met for the first time to discuss potential targets for the nascent atomic bomb. While Manhattan Project scientists had been pursuing the bomb with the single-minded desire to beat Hitler to the punch, the meeting produced the first official signals that the government was beginning to take a much broader view of the project: Such a weapon could be used not only to deter the Nazis, but to craft and maintain a U.S.-dictated post-war new world order.

Emerging Picture of Uranium’s Health Risks
Uranium, including depleted uranium (DU), is usually most dangerous to people when it gets inside the body, whether through ingestion, inhalation, or through breaks in the skin (though prolonged contact can also result in significant external radiation dose). Inside the body, uranium creates risks both as a toxic heavy metal and as a radioactive material. Additionally, there are some indications that synergisms might exist between these two types of health effects.
