Изотопи на кириумот

Кириумот (Cm) е вештачки елемент со атомски број 96. Бидејќи е вештачки елемент, не може да се даде стандардна атомска тежина и нема стабилни изотопи. Во 1944 година бил синтетизиран првиот изотоп, Cm, кој има 146 неутрони.

Познати се 19 радиоизотопи кои се движат од Cm до Cm. Исто така, постојат десет познати јадрени изомери. Најдолговечниот изотоп е Cm, со време на полураспад од 15,6 милиони години - ред на големина подолг од оној на кој било познат изотоп надвор од кириумот, и доволно долг за да се проучи како можен изумрен радиоизотоп што би се произвел со r-процес. Најдолговечниот познат изомер е Cm со време на полураспад од 1,12 секунди.
