FIELD: biotechnology.
SUBSTANCE: radioactive raw materials containing radioactive chemical elements or their isotopes, are treated with an aqueous suspension of bacteria of Thiobacillus in the presence of elements with variable valence. The radioactive raw materials are used as ores or radioactive wastes of nuclear cycles. The method is implemented to obtain polonium, radon, francium, radium, actinium, thorium, protactinium, uranium, neptunium, americium, nickel, manganese, bromine, hafnium, ytterbium, mercury, gold, platinum, and their isotopes.
EFFECT: invention enables to obtain valuable radioactive elements, to carry out the inactivation of nuclear wastes with the conversion of radioactive isotopes of the waste elements into stable isotopes.
