| Most of the transuranium elements have isotopes that disintegrate by fissioning in addition to emitting alpha particles. |
| Alpha emitting radionuclides emit alpha particles, each consisting of 2 protons and 2 neutrons. |
| The major disadvantage of thoria are the environmental issues due to the exposure to the alpha particles emitted by thorium. |
| 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. |
| The radioactive material generates ionising radiations, which include alpha particles, beta particles, X-rays and gamma rays. |
