what is californium used for

Cf-245 neutron therapy involves inserting a Cf-245 implant near the tumors so the neutrons strike the tumors more directly, which saves the healthy surrounding tissue from being damaged by the treatment. Because californium is a very efficient source … It is used in moisture gauges for the determination of water and oil-bearing layers in oil wells.

The most commonly used spontaneous fission neutron source is the radioactive isotope californium-252. This element is not found in nature and is formed by colliding curium with alpha particles (helium-4 ions). After a plane has been used for a while, the metal it's made from might weaken or crack.

An early use of NAA was the analysis of rocks brought back from the moon. The element is used in fuel rod scanners, portable metal detectors, and neutron radiography equipment in weapons and aircraft. Earn Transferable Credit & Get your Degree. This is called neutron radiography (NA). Think of this as using a fly swatter to kill a bug versus using filling the house with toxic gas to kill it. - Uses, Discovery & Properties, Curium: Element Discovery, Name & Properties, What is Dysprosium? {{courseNav.course.topics.length}} chapters | It is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium © copyright 2003-2020 Study.com. To learn more, visit our Earning Credit Page. Californium-252 is a very strong neutron emitter. Thomas uses cookies to ensure that we give you the best experience on our website. It has also been used as a target material for producing transcalifornium elements. Neutron activation analysis (NAA) is a way to identify various materials based on the subject material being struck by free neutrons. In the airline industry, it's used to check airplanes to make sure they are still safe. Get access risk-free for 30 days, It also is used to locate and analyze oil reserves, and to determine water levels in soils. Let's learn what Cf-252 is used for. It is used as a neutron emitter, providing neutrons for the start-up of nuclear reactors. - Definition & Facts, Using Telescopes, Spectroscopes & Probes to Investigate the Universe, Quiz & Worksheet - Chronic vs. Nuclear power plants work on the principle of fission where free neutrons (neutrons outside of the nucleus) split atoms, which releases energy. Soft enough to be cut with a razor blade, californium is pure metal. It decays releasing free neutrons that serve a variety of purposes such as: Neutron activation analysis (NAA) is a technique used to identify elements by allowing free neutrons from Cf-245 to strike a material generating isotopes of that element that decay. Well, in the case of Cf-252, there are many beneficial uses of the free neutrons it produces when it decays. As far as californium uses in everyday life, californium is also being used in medical applications, such as for the treatment of cervical cancer after radiation treatment proves ineffective. Terms and Conditions, It also used as an identifier to check Water and oil layers in oil wells. To start the fission process in a reactor a steady supply of neutrons is needed.
