Medical radioisotopes:
governments and industry must change practices to ensure security of supply

The OECD/NEA Steering Committee for Nuclear Energy calls on governments and industry to work together to implement fundamental changes in the molybdenum-99 supply chain to ensure long-term reliability of supply. Molybdenum-99 (99Mo) and its decay product, technetium-99m (99mTc), the most widely used medical radioisotope, are used in medical diagnostic imaging techniques that enable precise and accurate, early detection and management of diseases such as heart conditions and cancer, all in a non-invasive manner. Disruptions in the global supply chain of these medical isotopes over the past two years have had significant impacts on patients, who have had important diagnostic tests cancelled or delayed.

On 28 April, the OECD/NEA Steering Committee for Nuclear Energy formally endorsed a policy approach to restructure those aspects of the market that are currently functioning unsustainably, and to promote an internationally consistent approach to ensure the long-term, secure supply of medical radioisotopes. Although the supply situation has stabilised for the moment, it remains fragile and the Committee stresses that the underlying problem threatening security of supply – an unsustainable economic structure – remains to be adequately addressed.

The policy approach recognises the need for structural reform and recommends clear actions to governments for establishing an economically sustainable supply chain. In particular, it calls on:

The NEA High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR), established in 2009, developed the principles of this policy approach which should be applied by countries that have an impact on the global market, either as 99Mo/99mTc producers or consumers. The implementation of these principles, for which the HLG-MR is developing supporting recommendations, is essential to achieving change and security of supply. Unless actions are taken to ensure long-term security of supply, the OECD/NEA Steering Committee for Nuclear Energy warns that supply shortages could become commonplace over the next decade.

NEA membership consists of 33 countries. The mission of the NEA is to assist its member countries in maintaining and further developing, through international co‑operation, the scientific, technological and legal bases required for a safe, environmentally sound and economical use of nuclear energy for peaceful purposes. It strives to provide authoritative assessments and to forge common understandings on key issues as input to government decisions on nuclear energy policy and to broader OECD analyses in areas such as energy and the sustainable development of low‑carbon economies.
