Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the same as a helium atom as it does not contain any electrons but it is written with ...

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 ...

Back in 2007, physicists at the GSI heavy ion accelerator in Darmstadt, Germany, made a puzzling discovery. These guys were measuring the radioactive decay rates of praseodymium and promethium nuclei ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could ...
