Abstract

A new 99Mo production method is proposed through 99Tc (μ−, v) 99Mo muon nuclear-capture reaction with recycled 99Tc material. The 99Mo is a parent nucleus of 99mTc for imaging diagnostics. The 99Mo is produced in the 99Tc target, and the molybdate ion (MoO42−) is separated from the pertechnetate ion (99TcO4−). High 99Mo-specific activity is obtained, and no radioactive by-product is generated. The 99Tc material has an unlimited resource: it is a decay product of 99Mo and is contained in spent nuclear fuel. The 99Mo-specific activity and production activities of 99Mo and 99mTc are calculated assuming the reaction branching ratios.
