A radioactive decay chain and the spectrum obtained by the INTEGRAL observatory. Note the scale of the vertical axis -- about one gamma quantum an hour per 1cm2!

Other elements, like francium and plutonium, are only produced in trace amounts by the decay of uranium--and by trace amounts, I mean that if you gathered all the naturally occurring plutonium in ...

From the nine observed decay chains, the researchers then measured the 𝛼-particle energy and half-life of plutonium-227 to be about 8191 keV and 0.78 s, respectively.

The new nuclei — which fit into the periodic table between rutherfordium (element 104) and the as-yet-unnamed element 114 — were created in a single radioactive decay chain by Paul Ellison at ...

Radioactive close radioactiveWhen unstable atoms give off particles that can be harmful to humans. decay is a random close randomOccurring without a pattern. Unpredictable. In statistics where ...

Plutonium pits, the potent hearts of modern nuclear weapons, degrade over time. As these cores decay, so too does the certainty that they will work as designed when detonated. Los Alamos National ...
