Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A ...

The process by which unstable atomic nuclei transform into more stable configurations underlies a multitude of applications, from medical imaging to geochronology and nuclear power. Nuclear decay ...

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 ...

This video explores three different types of radioactive decay: alpha, beta and gamma. They all have different amounts of ionising power and penetration. Ionising Power describes how easily radiation ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through a stunning three-proton emission sequence, shedding light on nuclear ...

Researchers are exploring the use of radioactive waste to create ultra-long-life micro-nuclear batteries for specialized devices. These batteries, unlike consumer electronics power sources, harness ...
