Data services, data networks and user support 1. Collect accurate and up-to-date atomic and nuclear data, and disseminate to satisfy the needs of users from Member States 2. Co-ordinate networks of national and regional data centres, and promote the exchange of atomic and nuclear data for various applications 3.
