Изотопи на полониумот

Постојат 42 изотопи на полониум (84Po). Тие се со големина од 186 до 227 нуклеони. Сите тие се радиоактивни. 210Po со време на полураспад од 138.376 дена има најдолго време на полураспад од сите природни изотопи на полониум и е најчестиот изотоп на полониумот. Тоа е и најлесно синтетизираниот изотоп на полониумот. 209Po, кој не се јавува природно, има најдолго време на полураспад од сите изотопи на полониум со 124 години. 209Po може да се добие со користење на циклотрон за бомбардирање на бизмут со протони, како и 208Po.
