Plutonium costs on average of $4,000 per gram, but there are severe restrictions on who can buy it, as you can imagine.
Approx. 4 000 US $ for weapon-grade plutonium.
fantasy
The cost of weapons grade plutonium (more than 93 % Pu-239) is appreciated at 4 000 000 US $/kg.
roughly $85,000
The price of nuclear weapons grade plutonium is approx. 4 000 US $ for one gram, in 2010.
The price is estimated at 4 000 $.
The price will be probable 400 000 $.
In very round figures, the cost of enough Oralloy (93.5% HEU) or Plutonium to make a bomb is somewhere between $100,000 and $1,000,000, with Plutonium being a bit cheaper at this time.
Some plutonium chemical compounds; plutonium dioxide, plutonium nitride, plutonium carbide, plutonium nitrate, plutonium trifluoride, plutonium chloride, etc.
It costs $280 per gram, it is one of the most expensive elements.
Try buying Uranium or Plutonium.
Examples are: plutonium metal, isotope Pu-238, plutonium dioxide, plutonium sulfide, plutonium nitrate, plutonium carbide etc.
