Изотопи на родиумот

Природно настанатиот родиум (<sub>45</sub>Rh) има само еден стабилен изотоп, <sup>103</sup>Rh. Најстабилни радиоизотопи се <sup>101</sup>Rh со време на полураспад од 3,3 години, <sup>102</sup>Rh со време на полураспад од 207 дена и <sup>99</sup>Rh со време на полураспад од 16,1 дена. Триесет други радиоизотопи се одликуваат со атомска тежина која се движи од 88,949 u (<sup>89</sup>Rh) до 121.943 u (<sup>122</sup>Rh). Повеќето од нив имаат време на полураспад помало од еден час, освен <sup>100</sup>Rh (време на полураспад: 20,8 часа) и <sup>105</sup>Rh (време на полураспад: 35,36 часа). Исто така, постојат бројни мета состојби со најстабилен <sup>102m</sup>Rh (0,141 MeV) со време на полураспад од околу 3,7 години и <sup>101m</sup>Rh (0,157 MeV) со време на полураспад од 4,34 дена.
Примарниот режим на распаѓање пред единствениот стабилен изотоп, <sup>103</sup>Rh, е електронскиот зафат, а примарниот режим после е бета емисија. Примарниот распаден производ пред <sup>103</sup>Rh е рутениум, а примарниот производ после е паладиум.
