Isotopes of californium projectiles, mortar projectiles, rockets, bombs, land mines, and improvised explosive devices (IED). In the oil industry, Cf-252 neutron sources are used to find layers of petroleum and water in a well. Instrumentation is lowered into the well which bombards the formation with high energy neutrons to determine porosity, permeability, and hydrocarbon presence along the length of the borehole. Californium-252 has also been used in the treatment of serious forms of cancer. In patients suffering from certain types of brain and cervical cancer, Cf-252 can be used as a more cost-effective substitute for radium. Isotopes of californium Californium (Cf) is an
Californium compounds bound to the borate. Californium is the second-heaviest element for which an organometallic compound is known. CpCf (Cp = CH) was prepared from reaction of CpBe and CfCl on microgram scale and characterized by X-ray crystallography. Californium compounds Few compounds of californium have been made and studied. The only californium ion that is stable in aqueous solutions is the californium(III) cation. The other two oxidation states are IV (strong oxidizing agents) and II (strong reducing agents). The element forms a water-soluble chloride, nitrate, perchlorate, and sulfate and is precipitated as a fluoride, oxalate or hydroxide. If problems of availability of
