Interest in the neutron-emitting californium -2radioisotope as a radiotherapy nuclide has undergone a resurgence given recent efforts to fabricate HDR remotely afterloaded sources, and other efforts to create a miniature source for improved accessibility to a variety of anatomic sites. Therefore, HDR 252-Cf brachytherapy . Get information, facts, and pictures about californium at Encyclopedia.

Make research projects and school reports about californium easy with credible articles from our FREE, online encyclopedia and dictionary. A radioactive transuranic element, it was discovered by bombarding curium with alpha particles (helium ions). Since the lanthanide homologue of californium ( dysprosium) . A coming- of-age crossover novel about growing up, selling out, and fitting in. The first cube of the element had sides nanometers long. A human hair is 80nanometers thick.

The method used to make californium involved bombarding curium-2with alpha particles (helium-nuclei) using the cyclotron. The periodic table is a chart that shows how chemical elements are related to each other. Uranium is element number in the periodic table, so elements with atomic numbers greater than are said to be transuranium elements. Californium is the heaviest element that has been produced in weighable amounts.

English dictionary definition of californium.

Symbol Cf A synthetic transuranic element having isotopes with mass numbers from 2to 2and half -lives varying from milliseconds to 8years.

Applications include use as a neutron source in nuclear reactors, material scanners, certain types of cancer treatment and well logging in the oil industries. This week, we meet the element, californium. Following our blog on neptunium, the first transuranium element, californium was the sixth to be discovered.

It is similarly unstable and radioactive. Seaborg was one of the scientists who first synthesised it, and he was involved in the discovery of other transuranium elements too – leading to a .
