Isotop utama kalifornium
Iso­top Kalimpahan Paruh-idup (t1/2) Mode paluruhan Pro­duk 248Cf sintétis 333,5 hri α (100%) 244Cm SF (2,9×10-3 %) – 249Cf sintetis 351 thn α (100%) 245Cm SF (5,0×10-7 %) – 250Cf sintetis 13,08 thn α (99,92%) 246Cm SF (0,08%) – 251Cf sintétis 898 thn α 247Cm 252Cf sintetis 2,645 thn α (96,91%) 248Cm SF (3,09%) – 253Cf sintétis 17,81 hri β− (99,69%) 253És α (0,31%) 249Cm 254Cf sintétis 60,5 hri SF (99,69%) – α (0,31%) 250Cm

Kalifornium silih tunggil datu kimia sintétis antuk simbol Cf miwah wilangan atom 98. Datu puniki kapertama kasintesis warsa 1950 ring Laboratorium Nasional Lawrence Bérkléy (selanturné Laboratorium Radiasi Universitas California), antuk ngabombardir curium antuk partikel alpha (ion hélium-4). Punika datu radioaktip aktinida, datu transuranium kanem manados kasintésis, miwah ngelah bobot atom pinih tegeh kaping kalih saking samian datu sané sampun kaproduksi akéh antuk kacingak sareng panyingakan langsung (sesampun éinsteinium). Datu puniki kaaranin universitas miwah negara wagian Amérika Serikat saking California.

Panganggen

Kalifornium dados kaanggén antuk terapi kanker. Datu puniki silih tunggil wit neutron sané éfisién. Wiadin nika akéh potensi kagunaan anyar ring datu puniki.
