METHOD AND SYSTEM FOR CONCENTRATING RADIOACTIVE TECHNETIUM AS RAW MATERIAL FOR RADIOACTIVE DRUG AND LABELING COMPOUND THEREFOR AND COLLECTING THE SAME BY ELUTION

摘要

To use 99m Tc as a raw material for a radioactive medicine, a very small amount of 99m Tc in the high concentration Mo( 99 Mo) solution is purified and recovered with high yield without contamination of 99 Mo. 99m Tc with high purity is recovered by forming a high concentration Mo( 99 Mo) solution which contains radionuclides 99 Mo which is the parent nuclide of 99m Tc used for the radioactive medicine and the raw material for its labeled compound, forming a high concentration Mo ( 99 Mo) solution which contains radionuclides 99 Mo and 99m Tc by generating 99m Tc to a radioactive-equilibrium state, getting 99m Tc in the high concentration Mo( 99 Mo) 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 99m Tc with a desorbent from the activated carbon to which 99m Tc is adsorbed.
