| Alpha decay occurs when an atomic nucleus disintegrates by emitting alpha particles. |
| This was used on his electroscopes and on his ionisation chambers for the work that he did with alpha particles. |
| Alpha emitting radionuclides emit alpha particles, each consisting of 2 protons and 2 neutrons. |
| Most of the transuranium elements have isotopes that disintegrate by fissioning in addition to emitting alpha particles. |
| Alpha radiation is the stream of alpha particles emitted when radioactive materials disintegrate. |
| For instance, after five alpha particles have been emitted we are left with element 105, which is called dubnium. |
