Изотопи на берклиумот

Берклиумот (97Bk) е вештачки елемент и затоа не може да се даде стандардна атомска тежина. Како и сите вештачки елементи, тој нема стабилни изотопи. Првиот изотоп што беше синтетизиран бил 243Bk во 1949 година. Постојат дваесет познати радиоизотопи, од 233Bk до 253Bk (освен 235Bk и 237Bk) и шест јадрени изомери. Најдолговечниот изотоп е 247Bk со време на полураспад од 1.380 години.
