Изотопи на тулиумот

Природно настанатиот тулиум (69Tm) е составен од еден стабилен изотоп, 169Tm (100% природна застапеност). Определени се  39 радиоизотопи, од кои најстабилни се 171Tm со време на полураспад од 1,92 години, <sup>170</sup>Tm со време на полураспад од 128,6 дена, 168Tm со време на полураспад од 93,1 ден и 167Tm со време на полураспад од 9,25 дена. Сите преостанати радиоактивни изотопи имаат време на полураспад помало од 64 часа, а повеќето од нив имаат време на полураспад помало од 2 минути. Овој елемент има и 26 метасостојби, со најстабилни 164mTm (t1/2 5,1 минути), 160mTm (t1/2 74,5 секунди) и 155mTm (t1/2 45 секунди).

Познатите изотопи на тулиумот се движат од 144Tm до 183Tm. Примарниот режим на распаѓање пред најзастапениот стабилен изотоп, 169Tm, е електронски зафат, а примарниот режим после е бета-емисија. Примарните распадни производи пред 169Tm се изотопи на ербиумот, а примарните производи потоа се изотопи на итербиумот. Сите изотопи на тулиумот се или радиоактивни или, во случај на 169Tm, набљудувачки стабилни, што значи дека се предвидува дека 169Tm е радиоактивен, но не е забележан вистински распад.

## Тулиум-170
Тулиумот-170 има време на полураспад од 128,6 дена, се распаѓа со β−-распад околу 99,87% од времето и електронски зафат преостанатите 0,13% од времето. Поради неговите нискоенергетски емисии на Х-зраци, тој е предложен за радиотерапија и како извор во радиотермички генератор.
