  • Method of recovering enriched radioactive technetium and system therefor
    Patent number: 9236153
    Abstract: To use 99mTc as a raw material for a radioactive medicine, a very small amount of 99mTc in the high concentration Mo(99Mo) solution is purified and recovered with high yield without contamination of 99Mo. 99mTc with high purity is recovered by forming a high concentration Mo(99Mo) solution which contains radionuclides 99Mo which is the parent nuclide of 99mTc used for the radioactive medicine and the raw material for its labeled compound, forming a high concentration Mo(99Mo) solution which contains radionuclides 99Mo and 99mTc by generating 99mTc to a radioactive-equilibrium state, getting 99mTc in the high concentration Mo(99Mo) solution adsorbed to activated carbon selectively by feeding the solution to an adsorption column which has activated carbon, and undergoing desorption and purification treatment of 99mTc with a desorbent from the activated carbon to which 99mTc is adsorbed.
