cal·i·for·ni·um

 (kăl′ə-fôr′nē-əm)
n. Symbol Cf
A synthetic transuranic element having isotopes with mass numbers from 237 to 256 and half-lives varying from 21 milliseconds to 898 years. All isotopes are radioactive, chiefly by emission of alpha particles, and Cf-252 is a potent neutron emitter. Atomic number 98; melting point 900°C; specific gravity 15.1; valence 3. See Periodic Table.

[After California.]

cal·i·for·ni·um

(kăl′ə-fôr′nē-əm)
Symbol Cf A synthetic, radioactive metallic element of the actinide series that is produced from curium or berkelium. Californium emits a large number of neutrons and is used in the analysis of chemical components of substances. Its most stable isotope has a half-life of 800 years. Atomic number 98. See Periodic Table.

5kg of enriched 'weapons-grade' uranium, was a Californium Flux Multiplier (CFX) acquired by the company in 1974 and only decommissioned in 2006.
The same samples were also analyzed with mass spectroscopy (LA-ICP-MS) by Shiva Technologies, Syracuse, NY, detecting 78 elements ranging from lithium to californium and 108 isotopes ranging from 7Li to 249Cf.
But recall that there is also nothing durable about most antimatter, or Californium and the other exotic chemical elements lurking near the misty peak of the periodic table, or mayflies which die after minutes or days of adult life, or even the continent of Asia when we look at the long past and future of continental drift.
