==History==

In 1937, the Italian chemists Carlo Perrier and Emilio Segrè isolated Technetium using a cyclotron; it was the first artificially produced (synthetic) element.  Since this element has such a short half-life, it cannot be found in nature.<ref>http://education.jlab.org/itselemental/ele043.html</ref>  Before this time, it had been predicted but never found.<ref>http://www.rsc.org/periodic-table/element/43/technetium</ref>

The primary use of Technetium is for medical exploration as a tracer.  It can also be added to steel for corrosion resistance.  This not usually practical, however, since it is a radioactive material.
