The uranium oxide which is a yellow colored substance and is also called yellowcake. Uranium metal is very toxic and dangerous for human health. It emits alpha radiations that cause cancer and it is also chemically toxic for human health – much like lead. Formation of uranium in our universe happens only in a supernova (explosion) of stars.

Uranium metal 99% depleted U238 — Luciteria

Uranium-238, otherwise known as depleted uranium or "DU", is of the biggest "pretty stable" atoms that strong nuclear force can manage. That means the metal is actually quite low in radioactivity, relatively speaking, and the type of radioactivity it emits is composed of a comparatively heavy 4-man team composed of two protons and two neutrons.

Deconversion of Depleted Uranium Natural uranium extracted from the ground consists on average of uranium-238 (U 238) at 99.3% concentration and uranium-235 (U 235) at 0.7% concentration.The uranium-235 component must be enriched to between 3-5% for use in …

Depleted Uranium |

Depleted uranium is what is left over when most of the highly radioactive types (isotopes) of uranium are removed for use as nuclear fuel or nuclear weapons. The depleted uranium used in armor-piercing munitions and in enhanced armor protection for some Abrams tanks is also used in civilian industry, primarily for radiation shielding and aircraft balance control.

Plutonium (Element) | Infoplease

Plutonium is chemically reactive. It tarnishes in air, taking on a yellow cast when oxidized. It dissolves in hydrochloric, hydriodic, and perchloric acids and reacts with the halogens, carbon, nitrogen, and silicon. Pure plutonium metal may be prepared by reduction of the trifluoride, PuF 3, with calcium metal. Sixteen isotopes of plutonium

Radionuclide Basics: Uranium | Radiation Protection | US EPA

Uranium (chemical syol U) is a naturally occurring radioactive element. When refined, uranium is a silvery-white metal. Uranium has three primary naturally occurring isotopes isotopeA form of an element that has the same nuer of protons but a different nuer of neutrons in the nucleus, giving it a different atomic mass. For example, uranium has thirty-seven different isotopes, including

ASTM C1348 - 01(2008) Standard Specifiion for Blended

This specifiion applies to uranium oxides with a 235 U enrichment less than 5 %. 1.2 This specifiion includes chemical, physical, and test method requirements for uranium oxide powders as they relate to the suitability of the powder for storage, transportation, and direct reduction to UO 2 powder. This specifiion is applicable to


URANIUM Properties-Uranium is a metal that is hard but ductile and malleable. It is very heavy (21/2 times as heavy as steel) and is capable of taking a high polish. The polished metal, however, rather quickly oxidizes to a black surface. In powder form uranium is black and pyrophoric, ch­ ing on fire spontaneously upon exposure to air.
