Unstable atoms emit fast-moving particles that can damage cells in the human body. Some atoms are far more unstable than ...

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the ...

Radioactive sources contain radioactive material of a particular radionuclide (an unstable form of an element emitting radiation), which can vary based on the application for which the source was ...

Element 99 — mysterious and exceptionally radioactive — sits inconspicuously in the bottom row of the periodic table. Named for legendary physicist Albert Einstein, einsteinium has been one of the ...

After the nuclear power plant accident at Fukushima, scientists around the world went into high gear, trying to figure out how we could respond next time. And for chemists at Berkeley Lab, that means ...

The nuclear accident in Fukushima remains etched into people's memories. It was a catastrophe that caused huge amounts of radioactively contaminated water to be released, which the operators of the ...

Feb. 3 (UPI) --Scientists have, for the first time, measured the bond distance of einsteinium, one of the most radioactive and difficult to make elements on the periodic table. Researchers detailed ...

Indonesian officials say they have detected traces of radioactive cesium 137 at a clove plantation as the country searches ...

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability, according to a new study by an ...
