11. It was used in civil programmes which included californium production and reactor research. 12. Californium polyborate is unusual in that californium is covalently bound to the borate.13. Californium polyborate is unusual in that californium is covalently bound to the borate. 14. Californium slowly tarnishes in air at room temperature.15. Californium is only reduce or oxidize the + 3 ion in solution have failed.16. The high spontaneous fission rate of californium -252 was observed in these samples. 17. Californium in the skeleton adheres to bone surfaces before slowly migrating throughout the bone.18. Ionizing radiation emitted by californium on bone and in the liver can cause cancer. 19. Californium is the second-heaviest element for which an organometallic compound is known.20. Two crystalline forms exist for californium under normal pressure : one above and one below.
