Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation.

One tonne of uranium ore contains about 0. 2 milligrams of actinium.

Most americium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 100 grams of americium.

Owing to the complete absence of mountain building and glaciation since the Permian ( in many areas since the Cambrian ) ages, the outback is extremely rich in iron, aluminium, manganese and uranium ores, and also contains major deposits of gold, nickel, iron, lead and zinc ores.

Most curium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 20 grams of curium.

Naturally occurring uranium is not fissile because it contains 99. 3 % of U-238 and only 0. 7 % of U-235.

Coal contains a small amount of radioactive uranium, barium, thorium and potassium, but, in the case of pure coal, this is significantly less than the average concentration of those elements in the Earth's crust.

Natural uranium metal contains about 0. 71 % U-235, 99. 28 % U-238, and about 0. 0054 % U-234.

The remainder, depleted uranium, contains only 0. 2 % to 0. 4 % U-235.

RepU recovered from light water reactor ( LWR ) spent fuel typically contains slightly more U-235 than natural uranium, and therefore could be used to fuel reactors that customarily use natural uranium as fuel.

Highly enriched uranium ( HEU ) has a greater than 20 % concentration of < sup > 235 </ sup > U or < sup > 233 </ sup > U. The fissile uranium in nuclear weapons usually contains 85 % or more of < sup > 235 </ sup > U known as weapon ( s )- grade, though for a crude, inefficient weapon 20 % is sufficient ( called weapon ( s )- usable ); in theory even lower enrichment is sufficient, but then the critical mass for unmoderated fast neutrons rapidly increases, approaching infinity at 6 % < sup > 235 </ sup > U. For criticality experiments, enrichment of uranium to over 97 % has been accomplished.

Uraninite also always contains small amounts of the lead isotopes < sup > 206 </ sup > Pb and < sup > 207 </ sup > Pb, the end products of the decay series of the uranium isotopes < sup > 238 </ sup > U and < sup > 235 </ sup > U respectively.

Pyrochlore ore typically contains greater than 0. 05 % of naturally occurring radioactive uranium and thorium.

It contains calcium, niobium, tantalum, cerium, titanium, yttrium, and typically uranium and thorium, with some other metals.

Due to the alpha decay of thorium and uranium, monazite contains a significant amount of helium, which can be extracted by heating.

The uranium hexafluoride conversion product contains only natural, not enriched, uranium.

For example, natural uranium is not significantly radioactive, but pitchblende, a uranium ore, is 13 times more radioactive because of the radium and other daughter isotopes it contains.

Subsequent ammunition developments resulted in the M919 APFSDS-T ( Armor-Piercing Fin Stabilized Discarding Sabot with Tracer ) round, which contains a finned depleted uranium penetrator similar in concept to armor piercing munitions used in modern tanks.
