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 ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.

the researchers determined the energies and directions of the emitted beta particle and two alpha particles with high precision. This approach allowed the researchers to reconstruct the full decay ...

While beta-particle emitters like 177 Lu-DOTATATE (Lutathera ... their limitations---namely relapse within a few years---have ...

But alpha particles are also a relatively new ... in the thyroid cancer in a similar manner to the well-established beta particle emitter, iodine-131. This is possible because astatine is in ...
