Bringing Small Devices, Giving Design Advice: Introducing Radiation Protection Practices in Greece via the IAEA's Visiting Professor Program**

This paper examines how an International Atomic Energy Agency (IAEA) expert mission for technical assistance in the late 1950s to Greece was effectively transformed into a mission to achieve the IAEA's central objective: to consolidate its position as the leading global authority on radiation protection. The study focuses on the work of Alfred Maddock, a professor at the University of Cambridge. In 1959, Maddock arrived in Greece as part of one of the IAEA's original missions, contributing to an educational program on radioisotopes. Beyond providing educational services, Maddock accomplished something more significant. As the Agency's facilitator, he introduced radiation protection materials and concepts to the country in accordance with the IAEA protocols. He introduced dosimetry devices (film badges) and, at the same time, reviewed, modified, and created architectural plans for the laboratories of the Greek Nuclear Centre to meet the IAEA safety standards. It is argued that Maddock's visit to Greece transcended a mere one-sided enforcement process. Rather, it catalyzed a dynamic interaction between Greece and the IAEA, characterized by robust elements of mutual cooperation. This mission stands as a prime example of the gradual integration of IAEA culture within a member state, tailored to local needs and conditions.
