{{Main|Synthesis of precious metals}}

Rhodium is a fission product of [[uranium-235]]: each kilogram of fission product contains a significant amount of the lighter platinum group metals. [[Used nuclear fuel]] is therefore a potential source of rhodium, but the extraction is complex and expensive, and the presence of rhodium radioisotopes requires a period of cooling storage for multiple half-lives of the longest-lived isotope (<sup>101</sup>Rh with a [[half-life]] of 3.3 years, and <sup>102m</sup>Rh with a [[half-life]] of 2.9 years), or about 10 years. These factors make the source unattractive and no large-scale extraction has been attempted.<ref>{{cite journal|doi = 10.1595/147106705X35263|url = http://www.platinummetalsreview.com/pdf/79-90-pmr-apr05.pdf|title = Potential Applications of Fission Platinoids in Industry|year = 2005| last1 = Kolarik|first1 = Zdenek|last2 = Renard|first2 = Edouard V.|journal = Platinum Metals Review|volume = 49|issue = 2|pages = 79–90|doi-access = free}}</ref><ref>{{cite journal|title = Recovery of Value Fission Platinoids from Spent Nuclear Fuel.
