자연계에 존재하는 '''[[터븀]]''' 혹은 '''테르븀'''의 동위 원소는 1종으로 <sup>159</sup>Tb이 100% 존재한다. [[우라늄]]과 [[토륨]]의 자발 핵분열로 생성되는 생성되는 <sup>161</sup>Tb은 [[반감기]]가 6.9일로 자연계에 미량 존재한다.

터븀의 인공 동위 원소는 <sup>135</sup>Tb부터 <sup>171</sup>Tb까지 합성되었다. 이들 중 <sup>157</sup>Tb은 반감기가 71년 <sup>158</sup>Tb은 180년의 반감기를 가지고 있어서 터븀의 인공 동위 원소들 중 반감기가 가장 길다.
