Isotopes are different versions of the same element. Where Can I Find SAT Chemistry Practice Tests? It is used as a metal detector. Can Your Company Help Provide Critical Supplies? Cf-245 is a high quality source of neutrons. See They have the same number of protons, but different numbers of neutrons giving them different atomic masses. first two years of college and save thousands off your degree. Neutrons are used instead of x-rays because neutrons only interact with an atom's nucleus. Californium-252 (Cf-252) is one several isotopes of californium. credit-by-exam regardless of age or education level. - Discovery & Properties, What is Dysprosium Used For? The products of that decay can be analyzed to identify the elements present in the subject material. Californium-252 is a neutron emitter, making californium a non-reactor based or portable neutron source, which used for the analysis of neutron activation, as well as a neutron start-up source in some types of nuclear reactors.
