Five workers exposed to radiation at Japan nuclear lab

Five workers at a Japanese nuclear facility that handles plutonium have been exposed to high levels of radiation after a bag containing highly radioactive material apparently broke during equipment inspection, the country's ...

New plutonium discovery lights way to clean up nuclear waste

Plutonium has long been part of many countries' nuclear energy strategies, but scientists are still unlocking the mysteries behind this complicated element and seeing how they can use heavier, nuclear elements to clean up ...

Unexpected oxidation state for molecular plutonium discovered

Researchers at Los Alamos National Laboratory in collaboration with the University of California - Irvine (UCI) have uncovered a significant new chemical attribute of plutonium, the identification and structural verification ...

Time to tackle the UK's plutonium mountain

Professor Neil Hyatt, Research Chair in Radioactive Waste Management, calls for UK plutonium policy to be re-examined to allow swift immobilisation of UK's civil plutonium stockpile to maximise safety, security and affordability ...

Plutonium keeps its electrons close to home

Found in nuclear fuel and nuclear weapons, plutonium is an incredibly complex element that has far-ranging energy, security, and environmental effects. To understand plutonium, scientists at Pacific Northwest National Laboratory ...

ORNL achieves milestone with plutonium-238 sample

With the production of 50 grams of plutonium-238, researchers at the Department of Energy's Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for ...

Titan helps unpuzzle decades-old plutonium perplexities

First produced in 1940, plutonium is one of the most electronically complicated elements on Earth—and because of its complexities, scientists have been struggling to prove the existence of its magnetic properties ever since.
