When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavior of the waste, especially when it comes into contact with water. The microorganisms interact with released radionuclides and influence their mobility ..read more

Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium ..read more

The shells of turtles, tortoises, and sea turtles keep growing as long as the animals live—and some of them live a remarkably long time ..read more

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an innovative adsorbent known as plasma light amidoxime cellulose (PLAOC) to efficiently extract uranium from seawater ..read more

The Biden administration has agreed to provide Ukraine with depleted uranium shells to equip M1A1 Abrams tanks that the U.S. is sending there. Britain has already delivered tanks to Ukraine equipped with depleted-uranium shells ..read more

A research team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has managed to purify water containing uranium using a special kind of bacteria known as magnetotactic bacteria. The name derives from their ability to react to magnetic fields. They can accumulate dissolved heavy metal in their cell walls. These research findings also shed new light on the interaction between uranium and bioligands ..read more

Eight years ago, the data was sound but only suggestive, the evidence strong but circumstantial ..read more

The loss of a capsule of caesium-137, measuring 6mm by 8mm, dominated the news late last month. The capsule was found in the Western Australian outback on February 1, but in terms of losing radioactive material, we have been here before ..read more

The word "exotic" may not spark thoughts of uranium, but Tyler Spano's investigations of exotic phases of uranium are bringing new knowledge to the nuclear nonproliferation industry ..read more

Significantly higher arsenic and uranium concentrations in public drinking water have been linked to communities with higher proportions of Hispanic/Latino, American Indian/Alaskan Native, and non-Hispanic Black residents, according to a new study at Columbia University Mailman School of Public Health ..read more
