|---|---|---|---|---|---|
| Beta Particle | High-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.
🗑
|
||||
| Gamma Radiation | Electromagnetic radiation of high frequency (very short wavelength).
🗑
|

| Natural Transmutation | The conversion of one chemical element or isotope into another. This occurs either through nuclear reactions (which an outside particle reacts with a nucleus), or through radioactive decay (where no outside particle is needed).
🗑
|
||||
| Artificial Transmutation | Transmutation artificially created by scientists via particle accelerators or other machinery.
🗑
|
||||
| Fission | A nuclear reaction in which the nucleus of an atom splits into smaller parts, it often produces high powered radiation
🗑
|
||||
| Nuclear Chemistry | The subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties.
🗑
|
||||
| Alpha particle | Consist of two protons and two neutrons bound together into a particle identical to a helium nucleus, which is produced in the process of alpha decay.
🗑
|
||||
| Radioactive Decay | The process by which an unstable atomic nucleus loses energy by emitting ionizing particles (ionizing radiation).
🗑
|
||||
| Fusion | A reaction in which two atoms or particles are collided together and form a bigger particle, produces high amounts of energy.
🗑
|
||||
| Half-life | The period of time it takes for a substance undergoing decay to decrease by half.
🗑
