Marie Curie worked with radioactive material with her bare hands. More than 100 years later, Sophie Hardach travels to Paris ...

Sitting at the bottom of this row of chemical workhorses, this spectacularly radioactive element would be toxic to anyone who came near it, if only it could stop itself from vanishing. In fact, it ...

The discovery of a metal-rich star packed with both light and heavy elements hints at exotic stellar explosions and the role of ancient dwarf galaxies in seeding the cosmos with uranium and thorium.

More common than gold, uranium is abundant on Earth. But less than one percent of the naturally occurring element is useful ...

ORNL is the U.S.' only producer of promethium-147, an isotope of the element with a radioactive half-life of 2.6 years. Using a method developed last year, ...

This substance is the most radioactive natural element, a million times more so than uranium. It is so radioactive that it gives off a pale blue glow. Yet it would still take the Curies another ...

All actinides are radioactive, but uranium is one of the four most radioactive elements, alongside radium, polonium and thorium. You may like 'Neutron lifetime puzzle' may have a new solution; ...

Uranium enrichment concentrates one specific type of the atom to create a substance that can generate massive amounts of ...

A radioactive substance, either as an element or as a compound, may enter the body by one or more of four routes — namely, the lungs, the digestive tract, through cuts or abrasions, and the ...

In 1945, Oak Ridge National Laboratory discovered a rare radioactive element called promethium. Nearly 80 years later, scientists have unlocked it.

In a process similar to how bananas and Brazil nuts become radioactive, tobacco plants can absorb radioactive elements such as radium, lead-210, and polonium-210 from some fertilizers used on crops.

Moyer led a team that developed separation processes for removing the most radioactive element in one of the most voluminous nuclear wastes so it can be turned into glass to isolate it from the ...
