IN a recent article 1 a modification to the normally accepted close-packed face-centred cubic structure of δ-plutonium was suggested. The purpose of this was to give a continuous gradation ...

The only problem is its radio active and that means that when it decays it tends to fall apart. It is of course Plutonium and here to spell it out is Cambridge University's Ian Farnan. Plutonium's ...

CALORIMETERS are often calibrated by generating a known electric current within them and observing the deflexion of the measuring instrument when the system is in a steady state. This method may ...

During the Cold War, the US produced hundreds of plutonium pits each year at the Rocky Flats Plant in Colorado. However, ...

Beginning in the late 1950s, the U.S. met this challenge by developing nuclear batteries known as radioisotope thermoelectric generators (RTGs) and producing plutonium-238 (Pu-238) as their fuel, ...

This, as he found out, isn’t something you should do lightly, as the one he used ended up containing an interesting mix of radioactive materials, including small amounts of plutonium-239 ...

The component, called a “plutonium pit,” is the radioactive component that acts as a first stage ‘trigger’ apparatus used to initiate the detonation of the thermonuclear device. Plans call for the W87 ...

A new study has revealed alarming levels of plutonium contamination near Los Alamos, New Mexico, the site where the first ...

NDA officials are said to lean in favour of burying the plutonium deep under the sea, permanently locking it away safely in a ...

The component, called a “plutonium pit,” is the radioactive component that acts as a first stage ‘trigger’ apparatus used to initiate the detonation of the thermonuclear device.

Ed Miliband has been urged to preserve a 140-tonne stockpile of radioactive plutonium instead of burying it as dangerous waste. The material, which is made up of spent fuel from power plants ...
