From 1 μg to 100 t, depending on the conditions.
Today all the uranium mines in Colorado are closed.
The density of pure uranium metal is 19,1 g/cm3.
Uranium is a silvery-grey metal in both solid and liquid state, However on exposure to air it produces a black uranium oxide on its surface, which would happen much faster to liquid uranium than to solid uranium.
Uranium dioxide, nuclear grade, not enriched has a value greater 100 US $/kg.
Uranium is a solid, not a liquid. So it is sold by weight, not by volume. As of 25 July 2011 Uranium costs US $ 51.50per US pound or US $113 per kilogram of natural uranium in the form of the unrefined uranium oxide (U3O8).
Because the uranium dust is inhaled and accumulated in the lungs; long term inhalation of uranium (or uranium compounds, also liquid aerosols) can lead to lungs cancer. Handling a piece of uranium with gloves is not dangerous (excepting of course the irradiated uranium; in this case we use hot cells).
None. A pellet of uranium contains uranium, not coal.
Uranium is not used at home.
Uranium-235 is found in nature at about 0.7% concentration to uranium-238.
Afghanistan has now no uranium mines.
Since you have stated that the uranium is pure, it is therefore all uranium and contains no lead; lead is not uranium.
The majority of nuclear reactors use uranium as nuclear fuel.
Today all the uranium mines in Colorado are closed.
The density of pure uranium metal is 19,1 g/cm3.
there is not uranium in the sun. the nuclear fusion is due to hydrogen that fuses to helium
Cca. 50 kg of highly enriched uranium. Now nuclear bombs use plutonium, not uranium.
Approx. 70 US $ for 1 kg of nuclear reactor grade uranium doxide (with natural uranium); the enriched uranium is more expensive, depending on enrichment.
