Изотопи на итриумот

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

90Y постои во рамнотежа со неговиот матичен изотоп стронциумот-90, кој е производ на јадрено цепење.
