Outline of Final Research Achievements

Technetium-99m/Molybdenum-99 is one of the most important radioisotopes used in nuclear medicine for common diagnostic imaging technologies such as single photon emission computed tomography (SPECT). For long-term stable supply of Tc-99m/Mo-99, which is now at risk of global shortages due to aging reactors for the Mo-99 production and nuclear nonproliferation problems, we carried out feasibility studies on the development of an innovative accelerator-based Tc-99m/Mo-99 production technology via the Zr-96(α, n)Mo-99 reaction.
In this study, we have demonstrated the possibility of Mo-99 production with higher specific activity, less activation and by-products production than the other accelerator-based technologies, by measuring the neutron production and excitation functions of radioisotopes on zirconium induced by helium.

Academic Significance and Societal Importance of the Research Achievements

国内で最も多く利用されている放射性医薬品(テクネチウム:Tc-99m製剤)の原料となるモリブデン99(Mo-99)については、現在その供給量のほぼ100%を輸入に
依存しており、製造元の原子炉の老朽化や空輸でのトラブルによる供給不足が深刻な問題となっている。多大の費用と時間、社会的理解が不可欠である原子炉の新規制基準対応や、核不拡散上の懸念から、原子炉に依存しない加速器を用いた新たなMo-99製造技術の確立が期待されている。本研究で提案するMo-99製造技術が実現すれば、国内の放射性医薬品の長期的な安定供給の一翼を担うことが期待できる。
