Types of radioactive decay |
Decay type |
The particles involved |
Sub-core |
The type of decay associated with nuclear emission: |
Alpha Decay |
The decay type of an alpha particle emitted in the nucleus (a = 4,z = 2) |
(A ? 4,Z ? 2) |
Proton emission |
The decay type of a proton (p) emitted in the nucleus. |
(A ? 1,Z ? 1) |
Neutron emission |
The decay type of a neutron (n) emitted in the nucleus. |
(A ? 1,Z) |
Dual Proton emission |
A decay type that emits two protons simultaneously in the nucleus. |

Cluster decay |
The nucleus emits a cluster of smaller nuclei or other particles of a specific type (a 1,Z 1) |
(A ? A1,Z ? z1) + (A1,z1) |
Various beta decay types: |
Beta-decay |
an electron is emitted from the nucleus (e ? ) and a decay type of a counter-electric neutrino (νe) |
(A,z + 1) |
Positron emission (β + decay) |
The decay type of a positron (E +) and an electric neutrino (νe) emitted from the nucleus. |
(A,z ? 1) |
Electronic capture |
The nucleus absorbs an orbital electron and emits a neutrino's decay type (the decaying nucleus exists in the form of an unstable excited state). |
( A,Z ? 1) |
double beta decay |
|
( A , Z + 2) |
Dual electron capture |
The nucleus absorbs two orbital electrons and emits a decay type of two neutrinos (the nucleus of decay is unstable ??). the form of a stationary excitation state) |
( A,Z ? 2) |
Electron trapping associated with positron emission |
The nucleus absorbs an orbital electron and then emits a positron and two neutrino decay type. |
(A,Z? ) 2) |
Double Positron emission |
The decay types of two positron and two neutrinos emitted from the nucleus of an atom |
( A,Z ? 2) |
Conversion between nuclei of the same nucleus: |
homogeneous heterogeneous conversion |
Excited state nuclei emit high-energy photons (gamma rays) decay type |
( A , Z ) |
internal conversion |
Excited state nuclei transfer energy to orbital electrons, and the decay type of the orbital electrons from the atom |
( A , Z ) |
