How many uranium isotopes arebad
WebUranium is radiologically no big deal until you spray it with neutrons inside a reactor, whereupon some of it ceases to be uranium any more, and some of the short half life products are BAD news. The chemical toxicity is probably a bigger deal, but depending on exactly what we mean by Uranium (U, UO, U with some sulphur tacked on, U with some … WebNuclear waste is made of radioactive atoms generated after large atoms split. Nuclear reactors make nuclear waste during operation. The physics leverage of E=MC² makes nuclear waste uniquely concentrated; it’s both extraordinarily small and seriously hazardous.The relatively tiny amount of waste is intriguing in that its overall …

Uraninite used to be known as pitchblende (from pitch, because of its black color, and blende, from blenden meaning "to deceive", a term used by German miners to denote minerals whose density suggested metal content, but whose exploitation, at the time they were named, was either unknown or not economically feasible). The mineral has been known at least since the 15th century from silver mines in the Ore Mountains, on the German/Czech border. The type locality i… WebAtoms come in many different types: Carbon, Oxygen, Nitrogen, Sulfur, and so forth, and these different types are called elements. The number of protons in the nucleus of an atom determines what kind of element it is. Isotopes are versions of the same element, they have the same number of protons, but a different number of neutrons.
