Abstract

We have for the first time succeeded in separating ^99mTc from a MoO₃ sample irradiated with accelerator neutrons free from any radioactive impurities and in formulating ^99mTc-methylene diphosphonate (^99mTc-MDP). ⁹⁹Mo, the mother nuclide of ^99mTc, was produced by the ¹⁰⁰Mo(n; 2n)⁹⁹Mo reaction using about 14MeV neutrons provided by the ³H(d; n) ⁴He reaction at the Fusion Neutronics Source of Japan Atomic Energy Agency. The ^99mTc was separated from ⁹⁹Mo by sublimation and its radionuclide purity was confirmed to be higher than 99.99% by γ-spectroscopy. The labeling efficiency of ^99mTc-MDP was shown to be higher than 99% by thin-layer chromatography. These values exceed the United States Pharmacopeia requirements for a fission product, ⁹⁹Mo. Consequently, a ^99mTc radiopharmaceutical preparation formed by using the mentioned ⁹⁹Mo can be a promising substitute for the fission product ⁹⁹Mo, which is currently produced using a highly enriched uranium target in aging research reactors. A longstanding problem to ensure a reliable and constant supply of ⁹⁹Mo in Japan can be partially mitigated.
