Природниот рениум (75Re) е 37,4% 185Re, кој е стабилен (иако се предвидува дека ќе се распаѓа), и 62,6% 187Re, кој е нестабилен, но има многу долг време на полураспад (4,12×10 10години). Меѓу елементите со познат стабилен изотоп, само индиумот и телурот на сличен начин се појавуваат со стабилен изотоп во помала изобилство од долговечниот радиоактивен изотоп.
Препознаени се уште 36 други нестабилни изотопи, од кои најдолговечни се 183Re со време на полураспад од 70 дена, 184Re со време на полураспад од 38 дена, 186Re со време на полураспад од 3,7186 дена, 182Re со време на полураспад од 64,0 часа и 189Re со време на полураспад од 24,3 часа. Има и бројни изомери, од кои најдолговечни се 186mRe со време на полураспад од 200.000 години и 184mRe со време на полураспад од 177,25 дена. Сите други имаат време на полураспад помало од еден ден.
