Method for obtaining radioactive methyliodide vapors under dynamic conditions


A “reagent” preparation technique for producing radioactive methyl iodide vapors applying an isotope exchange reaction has been developed. A laboratory facility for conducting heterophase iodine isotopic exchange under dynamic conditions has been created. Comparative studies of various inert carriers used in chromatography have been carried out. The dependences of the isotopic exchange efficiency on the gas flow rate and the methyliodide concentration are established.
