Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe. The stable isotope 113 In is only 4.3% of
Indium has 39 known isotopes, ranging in mass number from 97 to 135. Only two isotopes occur naturally as primordial nuclides: indium-113, the only stable isotope, and indium-115, which has a half-life of 4.41 × 10 14 years, four orders of magnitude greater than the age of the Universe and nearly 30,000 times greater than half life of thorium ...

The oxides of indium in its preferred oxidation state of +3, namely In 2 O 3 and In(OH) 3 are weakly amphoteric; it forms anionic indates in strongly basic solutions. [112] Indium forms Zintl phases such as LiIn, Na 2 In and Rb 2 In 3. [113] Indium does not oxidize in air at ambient conditions. [109]

Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.
