That’s what makes the isotope uranium-235 so special—it’s fissile, so with a bit of finessing, it can support a nuclear chain reaction, ... causing the material to decay into uranium-233.

Nuclear energy is growing around the world after a twenty-five-year lull. Forty-four reactors are under construction in China, Russia and India alone (NEI), five in the United States, and over 600 ...

Although natural decay of U-235 means that this is unlikely to happen again, we humans have learned to take uranium ore and start a controlled fission process in reactors, beginning in the 1940s.

The combined results have allowed the KamLAND team to conclude that the heat flux due to the uranium and thorium decay chains is about 20 TW with an uncertainty of about 8 TW. While the KamLAND ...

It is well-known that a radioactive substance follows a fixed exponential decay, no matter what you do to it. The fact has been set in stone since 1930 when the “father” of nuclear physics Ernest ...

Nuclear reactors could be burning deep beneath the ground, two scientists have claimed. They say that uranium could become sufficiently concentrated at the base of Earth’s mantle to ignite self ...

This assumption followed naturally from the prevailing view of nuclear decay, which involved the emission, ... Probably each part will thus give rise to a chain of disintegrations.

Each day, 41,000 nuclear medical procedures are performed in the U.S. using Technetium-99, a radioisotope obtained from the decay of Molybdenum-99.
