Radioactivity is the act of emitting radiation spontaneously and is done by an atomic nucleus (unstable) to attain a more stable configuration by giving up some energy. Radioactivity is a physical, ...

Radioactive decay produces three flavors of emissions: alpha, beta, and gamma. Alpha particles comprise 2 neutrons and 2 protons. Because of their large mass and relatively slow speed, alpha particles ...

Observing the recoil caused by a single radioactive decay could help physicists spot exotic particles and possibly even dark matter. Radioactive decay is ubiquitous. It occurs everywhere on Earth and ...

The CERN-MEDICIS facility in Geneva, Switzerland has produced radioisotopes for medical research for the first time. This is the first step in the MEDICIS facility’s plans to make a large number 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 ...
