{{Short description|none}} {{more citations needed|date=May 2018}} {{Infobox cadmium isotopes}} Naturally occurring cadmium ({{chem2|_{48}Cd}}) is composed of 8 isotopes. For two of them, natural radioactivity has been observed, and three others are predicted to possibly decay though this has not been observed; it may be presumed the half-lives are extremely long. The two natural radioactive isotopes are {{chem2|^{113}Cd}} (beta decay, half-life {{val|8.04e15|u=years}}) and {{chem2|^{116}Cd}} (double beta decay, half-life {{val|2.69e19|u=years}}). The other three are {{chem2|^{106}Cd}}, {{chem2|^{108}Cd}} (double electron capture), and {{chem2|^{114}Cd}} (double beta decay); only lower limits on their decays have been set. Only three isotopes—{{chem2|^{110}Cd}}, {{chem2|^{111}Cd}}, and {{chem2|^{112}Cd}}—are theoretically stable. Among the isotopes absent in natural cadmium, the most long-lived are {{chem2|^{109}Cd}} with a half-life of 461.3 days, and {{chem2|^{115}Cd}} with a half-life of 53.46 hours. All of the remaining radioactive isotopes have half-lives that are less than 7 hours and the majority of these are less than 5 minutes. This element also has 12 known meta states, with the most stable being {{chem2|^{113m}Cd}} ({{t-half}} 13.9 years), {{chem2|^{115m}Cd}} ({{t-half}} 44.6 days) and {{chem2|^{117m}Cd}} ({{t-half}} 3.44 hours).
The known isotopes of cadmium range from {{chem2|^{95}Cd}} to {{chem2|^{132}Cd}}. The primary decay mode before the stable isotope {{chem2|^{112}Cd}} is electron capture to isotopes of silver, and after, beta emission to isotopes of indium.
<!-- The following paragraph needs more context --> A 2021 study has shown at high ionic strengths, cadmium isotope fractionation mainly depends on its complexation with carboxylic sites. At low ionic strengths, nonspecific cadmium binding induced by electrostatic attractions plays a dominant role and promotes cadmium isotope fractionation during complexation.<ref name="Cd-Ratié">{{cite journal|last1=Ratié|first1=Gildas|last2=Chrastný|first2=Vladislav|last3=Guinoiseau|first3=Damien|last4=Marsac|first4=Rémi|last5=Vaňková|first5=Zuzana|last6=Komárek|first6=Michael|date=2021-06-01|title=Cadmium Isotope Fractionation during Complexation with Humic Acid|url=https://doi.org/10.1021/acs.est.1c00646|journal=Environmental Science & Technology|volume=55|issue=11|pages=7430–7444|doi=10.1021/acs.est.1c00646|pmid=33970606 |bibcode=2021EnST...55.7430R |s2cid=234361430 |issn=0013-936X|url-access=subscription}}</ref>

== Cadmium-113m == {{Medium-lived fission products}}
'''Cadmium-113m''' is a cadmium radioisotope and nuclear isomer with a half-life of 13.9 years. In a normal thermal reactor, it has a very low fission product yield, plus its large neutron capture cross section means that most of even the small amount produced is destroyed in the course of the nuclear fuel's burnup; thus, this isotope is not a significant contributor to nuclear waste.
Fast fission or fission of some heavier actinides{{which|date=May 2018}} will produce {{chem2|^{113m}Cd}} at higher yields.
