Naturally occurring rhodium (45 Rh) is composed of only one stable isotope, 103 Rh. [4] The most stable radioisotopes are 101 Rh with a half-life of 3.3 years, 102 Rh with a half-life of 207 days, and 99 Rh with a half-life of 16.1 days. Thirty other radioisotopes have been characterized with atomic weights ranging from 88.949 u (89 Rh) to 121. ...
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 (101 Rh with a half-life of 3.3 years, and 102m Rh with a half-life of 2.9 years), or about 10 years. These ...

The ligand exchange rate at ruthenium and rhodium tends to be long, hence it can take a long time for a ruthenium or rhodium compound to react. [quantify] At Chernobyl, during the fire, the ruthenium became volatile and behaved differently from many of the other metallic fission products. Some of the particles which were emitted by the fire ...
At 3% fission products by weight, one ton of used fuel will contain about 400 grams of rhodium. The longest lived radioisotope of rhodium is 102m Rh with a half-life of 2.9 years, while the ground state (102 Rh) has a half-life of 207 days. [1] Each kilogram of fission rhodium will contain 6.62 ng of 102 Rh and 3.68 ng of 102m Rh.
About 338 nuclides are found naturally on Earth. These comprise 251 stable isotopes, and with the addition of the 35 long-lived radioisotopes with half-lives longer than 100 million years, a total of 286 primordial nuclides, as noted above.
