Segment 7A: Radioactive Decay We explore the nature of radioactivity. Segment 7A: Radioactive Decay We explore the nature of radioactivity and describes the types of radioactive decay that occur.

Hickory dickory dock, this nucleus could make a great clock. A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there’s nothing that it obviously ...

An atom has been caught spitting out a fundamental nuclear particle in fewer than 18 nanoseconds, setting a speed record for a particular type of radioactive decay. Many radioactive elements, ...

The blast is what people imagine. A sudden flash, a rising cloud, the moment when history splits into “before” and “after”.

If you would like to learn more about the IAEA’s work, sign up for our weekly updates containing our most important news, multimedia and more. Radiation is energy that moves from one place to another ...

The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...
