Isotop berkelium

Berkelium (97Bk) adalah sebuah unsur buatan, sehingga berat atom standarnya tidak dapat diberikan. Seperti semua unsur buatan, ia tidak memiliki satu pun isotop stabil. Isotop pertama yang disintesis adalah 243Bk pada tahun 1949. Ada 18 radioisotop yang diketahui, mulai dari 233Bk hingga 253Bk (dengan pengecualian 235Bk, 237Bk, dan 239Bk), dan 6 isomer nuklir. Isotop yang berumur paling panjang adalah 247Bk dengan waktu paruh 1.380 tahun.
