METHOD FOR PRODUCING PHARMPREPARATION WITH TECHNECIUM-99M Russian patent published in 1996 - IPC

FIELD: nuclear power engineering. SUBSTANCE: gel is prepared from molybdenum trioxide irradiated in neutron flux by dissolving it in sodium hydroxide solution. Zirconium-molybdenum gel is settled down by adding zirconyl chloride to molybdate while stirring it and bringing pH value to 6.3-6.8. Upon producing gel matrix, the latter is washed while stirring first by water volume three times as grear as gel volume and then twice by water volume equal to gel volume, and finally by 8% solution of sodium chloride in water, its volume being equal to that of gel. Pharmpreparation is obtained by washing out technecium-99M produced in gel matrix once a day. EFFECT: facilitated procedure. 1 tbl
