Polonium-210 used to poison Litvinenko available online

Radioactive polonium, which British medical experts believe was used to poison the former FSB officer Aleksandr Litvinenko, is available online at the website of the US company United Nuclear Scientific Equipment & Supplies, which offers 0.1-microcurie samples of polonium-210 at the cost of $69. However, the fatal polonium dosage is 1-2 millicuries, or 10 to 20 thousand times higher. The price of such quantity of polonium is $700 to $1,400. A notice on the United Nuclear website reads that polonium can be delivered only within US borders.
