Uranium

Uranium is a heavy, metallic, naturally Radioactive Element of Atomic Number 92. It has two principle isotope of uranium-235 and uranium-238 ( and very small quantities of Uranium-234). The proportions of natural uranium by weight are about 0.01% Uranium-234, 0.072% Uranium-235, and 99.27% U-238. Uranium-235 is used in the the nuclear industry because it is Fissionable by Thermal Neutrons . Natural uranium is extracted from uranium ore where it starts life as a processed uranium oxide (Yellow Cake).

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less
