Thorium
Th (232.038054)
Thorium is a naturally occurring radioactive chemical element with the symbol Th and atomic number 90. It was discovered in 1828 by the Swedish chemist Jons Jakob Berzelius and named after Thor, the Norse god of thunder. In nature, virtually all thorium is found as thorium-232, which undergoes alpha decay with a half-life of about 14.05 billion years. The element has no known biological role. [Wikipedia]. Thorium is found in many foods, some of which are cashew nut, almond, black walnut, and butternut. Thorium is a natural radioactive chemical element with the symbol Th and atomic number 90. In nature, virtually all thorium is found as thorium-232, and it decays by emitting an alpha particle, and has a half-life of about 14.05 billion years (other, trace-level isotopes of thorium are short-lived intermediates of decay chains). It is estimated to be about four times more abundant than uranium in the Earths crust and is a by-product of the extraction of rare earths from monazite sands. -- Wikipedia.
