Изотопи на холмиумот

Природниот холмиум (<sub>67</sub>Ho) содржи еден набљудувачко стабилен изотоп, <sup>165</sup>Ho. Табелата подолу наведува 39 изотопи кои опфаќаат <sup>140</sup>Ho до <sup>178</sup>Ho како и 40 јадрени изомери. Меѓу познатите вештачки радиоактивни изотопи; најстабилниот е <sup>163</sup>Ho, со полураспад од 4.570 години. Сите други радиоизотопи имаат полураспад не поголем од 1.117 дена во нивните основни состојби (иако метастабилниот <sup>166 m1</sup>Ho има полураспад од околу 1.200 години), а повеќето имаат полуживот под 3 часа.
