Isotopes of tin

{{Short description|none}} {{Infobox tin isotopes}} Tin (₅₀Sn) is the element with the greatest number of naturally abundant isotopes, 10. Seven, ^114-120Sn, are theoretically stable, while the remaining three, ¹¹²Sn, ¹²²Sn, and ¹²⁴Sn, are potentially radioactive to double beta decay, but no decay has been observed. This is generally attributed to the fact that 50 is a "magic number" of protons. In addition, 32 unstable tin isotopes are known, including tin-100 (¹⁰⁰Sn) and tin-132 (¹³²Sn), which are both "doubly magic". The longest-lived of these is tin-126 (¹²⁶Sn), with a half-life about 230,000 years; with all others less than a year and the majority under 20 minutes.

The number of known metastable states is very large, including a long series of low-lying states in odd isotopes from 117 on, which gives two nuclides with a longer life than any ground-state radioisotope other than 126: ^121mSn, half-life 43.9 years, and ^119mSn, half-life 293.1 days.

Tin-117m is a radioisotope of tin. One of its uses is in a particulate suspension to treat canine synovitis (radiosynoviorthesis).<ref>{{Cite web |title=Procedure for Use of Synovetin OA |url=https://www.nrc.gov/docs/ML2017/ML20178A657.pdf|work=nrc.gov }}</ref>

== <span class="anchor" id="Tin-121m1"></span> Tin-121m== {{Medium-lived fission products}} '''Tin-121m''' (^121mSn) is a nuclear isomer of tin with a half-life of 43.9 years, making it technically a medium-lived fission product.

In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce it at higher yields. For example, its yield from uranium-235 is 0.0007% per thermal fission and 0.002% per fast fission.<ref name="Chadwick">M. B. Chadwick et al, "Evaluated Nuclear Data File (ENDF) : ENDF/B-VII.1: Nuclear Data for Science and Technology: Cross Sections, Covariances, Fission Product Yields, and Decay Data", Nucl. Data Sheets 112(2011)2887. (accessed at https://www-nds.iaea.org/exfor/endf.htm)</ref>

==Tin-126== {{Long-lived fission products}} '''Tin-126''' is a radioisotope of tin and one of the only seven long-lived fission products. While tin-126's half-life of 230,000 years means a relatively low specific activity, its short-lived decay products, two isomers of antimony-126, emit a cascade of hard gamma radiation - at least 3 photons above 400 keV per decay - before reaching stable tellurium-126, making it a possible external exposure hazard, which the other long-lived fission products are not by comparison.

Tin-126 is in the middle of the mass range for fission products, so its yield is fairly low (but still dominates that for the element tin). Fission of the common fuels such as ²³⁵U and ²³⁹Pu into unequal halves is preferred, especially with thermal neutrons, as used in almost all current nuclear power plants.
