METHOD FOR PRODUCING SILVER RADIOISOTOPES WITHOUT A CARRIER Russian patent published in 2017 - IPC G21G1/12 

FIELD: chemistry.

SUBSTANCE: metallic mercury cadmium or high energy protons irradiated target material and distilled under a hydrogen atmosphere release spalogennyh nonvolatile products comprising silver radioisotopes on the surface of quartz. The resultant sample was transferred radioactive source in the starting zone termohromatograficheskoy silica column and it was heated in an inert gas stream, such as helium, comprising a pair of antimony. Calcination in the presence of trace amounts of silver reagent produced volatile antimonide, which is carried in the gas stream from the start area to the deposition area. Isolation of silver radioisotopes is selective, because Related silver radioisotopes other elements formed during the irradiation target cadmium, do not form volatile antimonides. Use of mercury as the target results in the formation of rhenium volatile antimonide, volatility which exceeds considerably the volatility of the desired product, whereby overlapping zones of the two compounds adsorbed slightly.

EFFECT: increased security personnel.
