This means that as more of these atoms decay you have a lower rate of radioactive decay. I know can be hard to wrap your head around, so let's model it with a six-sided die. Start with 100 objects.

A highly coveted children's toy from the 1950s is going on sale—and it contains real uranium. The Gilbert U-238 Atomic Energy Laboratory, which was released in 1950, was dubbed one of 'the 10 ...

A new study of the radioactive decay of manganese-54 counters previous measurements that suggest that the rate of decay is influenced by Earth’s orbit of the Sun. Mark Silverman of Trinity College in ...

Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.

To observe a radioactive decay that’s key to building a nuclear clock, scientists used the nuclear physics facility ISOLDE at CERN near Geneva (pictured). CERN. Share this: ...

Autunite, carnotite, torbernite and uraninite and are all minerals containing uranium. Uranium is a radioactive element, ...
