21. Most of these applications exploit the property of certain isotopes of californium to emit neutrons. 22. :: There is no need to invoke neutron stars, just try enriched californium . 23. Californium ( III ) oxychloride ( CfOCl ) was the first californium compound to be discovered.24. Californium ( III ) oxychloride ( CfOCl ) was the first californium compound to be discovered. 25. Californium ( III ) polyborate is unusual in that californium is covalently bound to the borate.26. Californium ( III ) polyborate is unusual in that californium is covalently bound to the borate. 27. Californium is the heaviest actinide to exhibit covalent properties, as is observed in the californium borate.28. Californium is the heaviest actinide to exhibit covalent properties, as is observed in the californium borate. 29. Californium -252 is a very strong neutron emitter, which makes it extremely radioactive and harmful.30. Fallout from atmospheric nuclear testing prior to 1980 contributed a small amount of californium to the environment.
