Изотопи на бизмутот

Бизмутот (83 Bi) има 41 познати изотопи, кои се движат од 184Bi до 224Bi. Бизмутот нема стабилни изотопи, но има еден многу долговечен изотоп; така, стандардната атомска тежина може да се даде како . Иако денес е познато дека бизмут-209 е радиоактивен, тој класично се смета за стабилен изотоп бидејќи има полураспад од приближно 2,01×1019 години, што е повеќе од милијарда пати повеќе од староста на вселената. Покрај 209Bi, најстабилни бизмутски радиоизотопи се 210mBi со полураспад од 3,04 милиони години, 208Bi со полураспад од 368.000 години и 207Bi, со полураспад од 32,9 години, од кои ниту еден не се јавува во природата. Сите други изотопи имаат полураспад под 1 година, најмногу под еден ден. Од природните радиоизотопи, најстабилен е радиогениот 210Bi со полураспад од 5,012 дена. 210mBi е невообичаено затоа што е јадрен изомер со полураспад  на повеќекратни редови на величина подолг од оној на основната состојба.

 Бизмут-213 
Бизмут-213 (213 Bi) има полураспад од 45 минути и се распаѓа преку алфа-емисија. Комерцијално, бизмут-213 може да се произведе со бомбардирање на радиум со закочено распаѓање на фотони од линеарен акцелератор на честички, кој го населува неговиот прогенитор актиниум-225 . Во 1997 година, конјугат на антитела со 213Bi бил користен за лекување на пациенти со леукемија. Овој изотоп исто така е испробан во програма за насочена алфа терапија (ТАТ) за лекување на различни видови на рак.  Бизмут-213 се наоѓа и во ланецот на распаѓање на ураниум-233, кој е гориво кое го одгледуваат ториумските реактори.
