Actually, Technetium was discovered in platinum ore from Colombia in 1932 using x-ray spectroscopy by Walter Noddack and Ida Tacke in Berlin. Emilio Segrè and Carlo Perrier out of Berkeley produced it artifically in 1937. Technetium is used for radiometric body imaging in the medical field.

Wow, I didn't know it had been found in nature. I always had heard that technetium, Tc, was manufactured, to fill the gap in the periodic table. The two elements on either side were known, but nobody had ever seen the missing one until it was created in laboratory conditions.
