Plutoniumisotop
Plutonium, like most metals, has a bright silvery appearance at first, much like nickel, but it oxidizes very quickly to a dull gray, although yellow and olive green are also reported. At room temperature plutonium is in its α (alpha) form. This, the most common structural form of the element (allotrope), is about as hard and brittle as gray cast iron unless it is alloyed with other metals to make it soft … WebMar 17, 2015 · I know, that in most cases, plutonium isotope separation is not needed, because there is no need to separate its fissile isotopes. But there is an exception: radioisotope thermoelectric generators (used to power remote devices such as spacecraft and unmanned polar equipment) need 238 P u. I think, Plutonium can be separated from …
