자연계에 존재하는 [[루테늄]]의 [[안정 동위 원소]]는 <sup>96</sup>Ru, <sup>98</sup>Ru, <sup>99</sup>Ru, <sup>100</sup>Ru, <sup>101</sup>Ru, <sup>102</sup>Ru, <sup>104</sup>Ru이 있다. <sup>96</sup>Ru은 β<sup>+</sup>β<sup>+</sup>붕괴를 통해 <sup>96</sup>Mo으로 붕괴할 것으로 예측되지만 아직 관찰되지 않았으며, 어쩌면 예측과 다르게 붕괴하지 않을 수 있다.

루테늄의 안정 동위 원소들 중 <sup>101</sup>Ru, <sup>102</sup>Ru, <sup>104</sup>Ru은 [[자발 핵분열]]이나 [[원자로]]의 [[핵분열]]로 생성되기도 한다.

인공적으로 합성된 루테늄의 동위 원소는 <sup>87</sup>Ru부터 <sup>120</sup>Ru까지 합성되었었다.
<sup>106</sup>Ru은 핵분열 생성 방사성 동위 원소로 [[반감기]]는 373.59일이다.
