 Cobalt - Wikipedia, the free encyclopedia
Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive tracer and cancer -treatment agent.
Co-60 is useful as a gamma ray source partially because it can be produced - in known quantity, and very large amounts - by simply exposing natural cobalt to neutrons in a reactor for a given time.

 cobalt
Cobalt-60, an artificial isotope, is an important gamma ray source, and is extensively used as a tracer and a radiotherapeutic agent.
Cobalt molybdenum alloys are used for the desulfurization of high-sulfur bituminous coal, and cobalt iron alloys in the hydrocracking of crude oil shale and in coal liquefaction.

 nuclear power - is nuclear power really really dangerous? An investigation of the perceived problems
the longest lived artificial radioactive isotope, is produced from its stable isotope cobalt-59, by neutron irradiation in a nuclear reactor.
Gamma radiation from cobalt-60 has been used in place of X rays or alpha rays from radium in the inspection of industrial materials to reveal internal structure, flaws, or foreign objects; in cancer therapy; in sterilization studies; and in biology and industry as a radioactive tracer.
Because of its relatively short half-life (eight days), iodine-131 is probably not the most hazardous fallout isotope; yet, excessive amounts of radiation from this isotope can lead to metabolic disturbances and an increased incidence of thyroid cancer, especially in children.

 Quiz #3 Spring 2001
(c) Cobalt-60 does not occur in nature, so if you want to use it as a medical isotope it has to be produced from naturally occurring Co-59.
Write a nuclear equation that shows how you could produce cobalt-60 from cobalt-59 using neutron activation.
Given a list of the stable isotopes for a particular element, predict how each radioisotopes would decay (i.e., by beta-minus emission or by beta-plus emission).

 Useful Tables
Although the concept of the enhanced fallout "cobalt bomb", in which radioactive Co-60 is produced by fusion neutrons, is well known this isotope is not known to have been seriously considered for weapons applications.
This isotope is produced by the decay of tritium and so accumulates in fusion boosting reservoirs as an undesirable contaminant due to its high neutron absorption.
Due to the large cross section for the (n,t) reaction at high neutron energies this isotope can breed substantial quantities of tritium in a fusion-driven chain reaction and thus serve as a fusion fuel.

 Interview with Steve T. Laflin, Internal Isotopes Inc.: TWST
Today those operations in Idaho include reactor-produced isotope, primarily Cobalt 60, which is used in some radiography devices, but primarily in gamma knife machines, and also contract manufacturing of flood sources or nuclear sealed calibration sources.
For the reactor isotopes, we plan to expand the processing capabilities here so that we can increase the list of isotopes we produce in the reactor.
I think the logistics of handling some of these isotopes create openings in the marketplace for us to supply some products, and I’m fairly convinced that there’s always a place for a company that is willing to work hard and try to do right by its customers.

 SELLAFIELD AS HEAVILY CONTAMINATED WITH RADIOACTIVITY AS CHERNOBYL
The analyses carried out for Greenpeace by the University of Bremen also found cobalt-60 values of up to 40 becquerels per kilogram, and pollution from caesium -137 in concentrations of up to 9,400 becquerels per kilogram, seven miles from the UK reprocessing plant.
In soil sampled seven miles away from the Sellafield plant, pollution from this isotope is as much as 30,000 becquerels per kilogram.
This is the conclusion emerging from the analyses of soil samples from both are as commissioned by Greenpeace to the University of Bremen (1).
