An alpha particle is also a helium-4 nucleus, so it is written as \(_{2}^{4}\textrm{He}\) and is also sometimes written as \(_{2}^{4}\textrm{\alpha}\) A beta particle has a relative mass of zero ...

An unstable nucleus can emit a fast-moving electron called a beta (β) particle, to become more stable. Beta radiation is made up of a stream of beta particles emitted from unstable nuclei.

Through the weak nuclear force, one quark flavor can transmute into another. However, current data and theory indicate that ...

While beta-particle emitters like 177 Lu-DOTATATE (Lutathera) have become standard as highly effective and well-tolerated therapy, their limitations---namely relapse within a few years---have ...
