Armaments Tungsten, usually alloyed with nickel and iron or cobalt to form heavy alloys, is used in kinetic energy penetrators as an alternative to depleted uranium, in applications where uranium's radioactivity is problematic even in depleted form, or where uranium's additional pyrophoric properties are not required (for example, in ordinary small arms bullets designed to penetrate body armor).

Grades Slightly enriched uranium (SEU) Slightly enriched uranium (SEU) has a 235U concentration of 0.9 to 2 .

Iraqi blogger Layla Anwar writes a detailed post about the contamination in Falluja resulting from depleted uranium and white phosphorous used in the war on Iraq and the cover up preventing thorough research.

Isotope separation Natural uranium consists of 99.3 uranium 238 and 0.7 uranium 235, but only the latter is fissile.

In 1941 he began working with uranium hexafluoride, the only known gaseous compound of uranium, and was able to separate uranium 235.

This was then heated to form uranium trioxide, which was reduced to highly pure uranium dioxide.

The high uranium content makes carnotite an important uranium ore and also radioactive.

The NDRC Committee on Uranium became the S 1 Uranium Committee of the OSRD the word uranium was soon dropped for security reasons.

The next form are aircraft delivered munitions.

The U.S. stockpile consisted of 39 of these weapon ready munitions.

Traditionally, development flows were unidirectional, going from the wealthy North to the impoverished South.

Thus, radium is found in tiny quantities in the uranium ore uraninite and various other uranium minerals, and in even tinier quantities in thorium minerals.

Impoverished, Charles could not obtain sufficient support to mount a serious challenge to Cromwell's government.

Since it is chemically identical to the most common isotope, uranium 238, and has almost the same mass, it proved difficult to separate.

(235U is only 1.26 lighter than 238U.

By September 1944, 14.9 million women were working in munitions production.

Some states have delivered automatic weapons, ammunition, and rocket propelled grenades.

Actinium 227 occurs in uranium ore.

Under pressure from Kutuzov, the Austrians agreed to supply munitions and weapons in a timely and sufficient manner.

A relatively simple gun type fission weapon was made using uranium 235, an isotope that makes up only 0.7 percent of natural uranium.

The Quraysh were the guardians of the Kaaba within the town of Mecca and was the dominant tribe of Mecca upon the appearance of Islam.

And then we get to uranium.

For example, ν 2.5 for uranium 235.

It was at this battle, regardless of exactly when and where this occurred, that a defining moment of Epaminondas's early life would happen.

This is a bullet coming from a very large ammunition company in the United States.

Uranium is used in the production of nuclear power.

Uranium is a constituent of most rocks, dirt, and of the oceans.

Aggregate U 235 production About of uranium enriched to 89 uranium 235 was delivered to Los Alamos by July 1945.

The most common ionic forms are (brown red), (green), (unstable), and (yellow), for U(III), U(IV), U(V), and U(VI), respectively.

The PKMT 7.62mm (7.62x54mm R) coaxial machine gun weighs about 10.5 kg while the ammunition box carries 250 rounds (7,000 rounds carried) and weighs an additional 9.5 kg.

Pitchblende, after removal of the radioactive elements uranium and thorium, was more radioactive than the uranium and thorium combined.

Work was proceeding on three different techniques for isotope separation to separate uranium 235 from uranium 238.

At the time, there was a limited source of pure uranium.

The half life of uranium 238 is about 4.47 billion years and that of uranium 235 is 704 million years, making them useful in dating the age of the Earth.

Bromides and iodides of uranium are formed by direct reaction of, respectively, bromine and iodine with uranium or by adding to those element's acids.

This may indicate possible contamination by small amounts of bacteria, underground sources of radiation causing the 14N(n,p) 14C reaction, direct uranium decay (although reported measured ratios of 14C U in uranium bearing ores would imply roughly 1 uranium atom for every two carbon atoms in order to cause the 14C 12C ratio, measured to be on the order of 10 15), or other unknown secondary sources of carbon 14 production.

The uranium was seized in a sting operation.

Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (), and diuranium trinitride ().

Actinium 227 is a decay product of uranium 235.

And you have the uranium mining that you have to deal with.

For natural uranium, about 49 of its alpha rays are emitted by each of 238U atom, and also 49 by 234U (since the latter is formed from the former) and about 2.0 of them by the 235U.

One tonne of natural uranium in ore contains about 0.2 milligrams of actinium 227, and one tonne of natural thorium contains about 5 nanograms of actinium 228.

Delays gave the French time to bring up and of ammunition from the railhead at Bar le Duc to Verdun.

The reduction of by hydrogen produces uranium trichloride () while the higher chlorides of uranium are prepared by reaction with additional chlorine.

And with current reactor technology we really don't have very much uranium.
