Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

For the first time, an international research team has succeeded in observing a two-photon decay on a so-called bare atomic nucleus from which the entire electron shell has been removed. The ...

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 ...

Two billion years ago, Gabon hosted Earth's only known natural nuclear reactor. This ancient reactor operated cyclically for ...

Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable ...

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 ...

Beijing Betavolt New Energy Technology Company Ltd claims to have developed a miniature atomic energy battery that can generate electricity stably and autonomously for 50 years without the need for ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...
