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. ...
Rhodium is a group 9 element (cobalt group). ... The most stable radioisotopes are 101 Rh with a half-life of 3.3 years, 102 Rh with a half-life of 207 days, ...
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.
As the longest-lived radioactive isotope ruthenium-106 has a half-life of only 373.59 days, it has been suggested that the ruthenium and palladium in PUREX raffinate should be used as a source of the metals after allowing the radioactive isotopes to decay. [4] [5] After ten half life cycles have passed over 99.96% of any radioisotope is stable ...
Group 9, by modern IUPAC numbering, [1] ... Rhodium was discovered in 1803 by William Hyde Wollaston, [7] ... Cobalt-60 is a commercially important radioisotope, ...
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.
This page lists radioactive nuclides by their half-life.
