Sep 21, 2022 · Plutonium has been described as the world’s most dangerous element. In popular culture, it conjures threatening images either of fearsome explosive destruction or rampant mutagenic radioactivity, and its status as a controlled substance further recalls secretive government machination.
Sep 19, 2014 · BBC News. Plutonium may be the most feared and fearsome substance in the entire periodic table. It's best known as the main ingredient of atomic bombs like the infamous Fat Man,...
Mar 19, 2020 · What is Plutonium? Printable Version. Plutonium has five "common" isotopes, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242. All of the more common isotopes of plutonium are "fissionable"—which means the atom's nucleus can easily split apart if it is struck by a neutron. The various isotopes of plutonium have been used in a number of applications.
Jan 7, 2021 · Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
