All the remaining radioactive isotopes have half-lives that are less than 2.7 years, and majority of the half lives only last for 20 minutes.
Nineteen radioisotopes of californium have been characterized, the most stable being 251Cf with a half-life of 898 years, 249Cf with a half-life of 351 years, and 250Cf with a half-life of 13 years.

BUT overall I am too tiny to be even seen!
My Home(Body, Planet, Universe)
Although californium does not occur naturally on Earth, Cf and its decay products occur in the universe; their electromagnetic emissions are observed in the spectra of supernovae.

My StoryI am named after the state of California and the University of California. I was discovered by Glenn T. Seaborg, Stanley G. Thompson, Albert Ghiorso, and Kenneth Street, but mainly produced by Ghiorso in 1950.
I am a manmade element that was made by bombarding curium with helium ions.
I am sold at $100 per gram, and since May 1975, 63 milligrams have been produced and sold.
I am also thought to be the cause of steller explosions called supernovae.
I was the sixth transuranium element to be discovered.
I am quite evil as well...
I cause cancer, immune system damage, leukemia, miscarriages, fertility problems.
