A Chinese company has unveiled a battery smaller than a coin that its makers say can generate steady electricity for fifty ...

A Florida startup has launched what it says is the first commercial demonstration of a nuclear-powered satellite technology, testing a power source that could allow future spacecraft and autonomous ...

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 ...

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 ...

The proliferation of nuclear power in space got a little more real Tuesday with the launch of a small satellite developed by ...

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 ...

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 ...
