Californium is found often in mineral mining and medical treatments. Californium has a. number of applications as it is a strong neutron emitter. It is a. useful neutron producer in nuclear reactions. it is also used in the treatment of cancers and analysers of coal. Californium was used in Russia to produce Oganesson in 2006, element 118. It is a solid metal at room temperature and it has a melting point of 900°c and a boiling point of 1470°c.
