Изотопи на полониумот

Постојат 42 изотопи на полониум (<sub>84</sub>Po). Тие се со големина од 186 до 227 нуклеони. Сите тие се радиоактивни. <sup>210</sup>Po 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. <sup>209</sup>Po, кој не се јавува природно, има најдолго време на полураспад од сите изотопи на полониум со 124 години. <sup>209</sup>Po може да се добие со користење на циклотрон за бомбардирање на бизмут со протони, како и <sup>208</sup>Po.
