Изотопи на итриумот

Природниот итриум (<sub>39</sub>Y) е составен од еден изотоп итриум-89. Најстабилни радиоизотопи се <sup>88</sup>Y, кој има време на полураспад од 106,6 дена и <sup>91</sup>Y, со време на полураспад од 58,51 дена. Сите други изотопи имаат време на полураспад помал од еден ден, освен <sup>87</sup>Y, кој има време на полураспад од 79,8 часа и <sup>90</sup>Y, со 64 часа. Главен режим на распаѓање под стабилниот <sup>89</sup>Y е електронскиот зафат, а доминантен режим по него е бета-емисијата. Определени се својствата на 35 нестабилни изотопи.
<sup>90</sup>Y постои во рамнотежа со неговиот матичен изотоп стронциумот-90, кој е производ на јадрено цепење.
