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.

While beta-particle emitters like 177 Lu-DOTATATE (Lutathera) have become standard as highly effective and well-tolerated ...

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