Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

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 ...
