Isotop kurium

**[[Kurium]]** (**<sub>96</sub>Cm**) adalah sebuah unsur buatan dengan nomor atom 96. Karena ia merupakan unsur buatan, berat atom standarnya tidak dapat diberikan, dan ia tidak memiliki satu pun isotop stabil. Isotop pertama yang disintesis adalah 242Cm pada tahun 1944, yang memiliki 146 neutron.

Ada 19 radioisotop yang diketahui, mulai dari 233Cm hingga 251Cm. Ada juga sepuluh isomer nuklir yang diketahui. Isotop berumur paling panjang adalah 247Cm, dengan waktu paruh 15,6 juta tahun – satu urutan besaran lebih lama daripada seluruh isotop setelah kurium yang diketahui, dan cukup lama untuk dipelajari sebagai radionuklida yang mungkin punah yang mungkin dihasilkan oleh proses r. Isomer yang berumur paling panjang adalah 246mCm dengan waktu paruh 1,12 detik.
