californium
n 1: a radioactive transuranic element; discovered by bombarding
curium with alpha particles [synonym: {californium}, {Cf},
{atomic number 98}]

californium
Symbol: Cf
Atomic number: 98
Atomic weight: (249)
Radioactive metallic transuranic element. Belongs to actinoid series.
Cf-251 has a half life of about 700 years. Nine isotopes are known.
Cf-252 is an intense {neutron} source, which makes it an intense
{neutron} source and gives it a use in {neutron} activation analysis
and a possible use as a radiation source in medicine. First produced
by Glenn T. Seaborg and associates in 1950.
