Californium

Californium can also be used in nuclear synthesis of higher mass elements; ununoctium (element 118) was synthesized by bombarding californium-249 atoms with calcium-48 ions.

In addition, californium-249 and californium-251 can cause tissue damage externally, through gamma ray emission.

The most stable of californium's twenty known isotopes is californium-251, which has a half-life of 898 years.

Californium (CURRENCY:CF) traded flat against the U.S. dollar during the twenty-four hour period ending at 15:00 PM E.T. on November 21st.

About 65% of that californium will be deposited in the skeleton, 25% in the liver, and the rest in other organs, or excreted, mainly in urine.

An article entitled "Facts and Fallacies of World War III" in the July 1961, edition of Popular Science magazine read "A californium atomic bomb need be no bigger than a pistol bullet.

Californium-249 has a relatively long half-life (352 years), weak spontaneous fission and strong γ-emission that facilitates its identification.

Californium-252, with a half-life of about 2.64 years, is the most common isotope used and is produced at the Oak Ridge National Laboratory in the United States and the Research Institute of Atomic Reactors in Russia.

Californium in the skeleton adheres to bone surfaces before slowly migrating throughout the bone.

Characteristics Physical properties Californium is a silvery white actinide metalsfn with a melting point of convert and an estimated boiling point of convert.sfn The pure metal is malleable and is easily cut with a razor blade.

Difficulty in studying its properties is due to einsteinium-253's conversion to berkelium and then californium at a rate of about 3% per day.

During the storage and before the fuel disposal, most of it beta decays to californium-249.

For example, the nuclear fusion of californium -249 and carbon -12 creates rutherfordium -261.

However, when the research team synthesized element 98, they could not think of a good analogy for dysprosium, and instead named the element californium in honor of the state in which it was synthesized, California.

In a thermal reactor, much of it will therefore be converted to berkelium-250 which quickly decays to californium-250.

Ionizing radiation emitted by californium on bone and in the liver can cause cancer.

It decays with a half-life of 330 days to californium -249, which is a strong emitter of ionizing alpha particles.

It is an α-emitter with a half-life of 20.47 days, a relatively weak γ-emission and small spontaneous fission rate as compared with the isotopes of californium.

Once in the body, only 0.05% of the californium will reach the bloodstream.

The EsF 3 crystal structure is hexagonal, as in californium(III) fluoride (CfF 3 ) where the Es 3+ ions are 8-fold coordinated by fluorine ions in a bicapped trigonal prism arrangement.
