Изотопи на антимонот

Антимонот (Sb) се јавува во два стабилни изотопи, Sb и Sb. Постојат 37 вештачки радиоактивни изотопи, од кои најдолговечни се Sb, со време на полураспад од 2,75856 години; Sb, со време на полураспад 60,2 дена и Sb, со време на полураспад 12,35 дена. Сите други изотопи имаат време на полураспад помалку од 4 дена, повеќето помалку од еден час. Има и многу изомери, од кои најдолготрајниот е Sb со време на полураспад 5,76 дена.
Освен берилиумот, антимонот е најлесниот елемент забележан дека има изотопи способни за алфа-распаѓање. Sb се гледа дека е подложен на овој начин на распаѓање. Некои светлосни елементи, имено оние во близина на Be, имаат изотопи со одложена алфа-емисија (по протонска или бета-емисија) како ретка гранка.
