Technetium

Technetium is a short-lived gamma ray-emitting nuclear element, used in nuclear medicine for a wide variety of diagnostic tests. Long-lived isotopes are produced commercially and are by-products of fission of uranium-235 in nuclear reactors and are extracted from nuclear fuel rods. Because no isotope of technetium has a half-life longer than 4.2 million years, its detection in 1952 in red giants, which are billions of years old, helped bolster the theory that stars can produce heavier elements.

1937 by Carlo Perrier and Emilio Segre, Italy.
