Material/Methods: Data on RT center operations during the war was collected by the Grigoriev Institute for Medical Radiology for the IAEA DIRAC database with last update in January 2023. This included information on equipment, staffing, and patient volumes. Additional information about changes in availability of trainings, government initiatives, other projects related RT were collected from open sources. Results: As of early 2022, unoccupied territories had 44 Co-60 machines and 33 linear accelerators. The 2022 invasion led to widespread RT center closures, with disruptions caused by halted linear accelerator operations and inability to perform source exchanges. RT patient volume in 2022 declined by 5,500 (-11%) compared to 2021. Significant staffing redistribution occurred, with 68% of regions reporting staffing changes exceeding 25%. It seemed that the situation in RT would worsen with each year of the protracted war. But the changes we are observing surprisingly indicate the reverse process: • public policy: the name of the doctors has been changed to radiation oncologists in accordance with international standards. It is planned to change the training system also. There is a process of recognition of medical physicists as a medical specialty. • procurement of equipment: The state has purchased 21 Linac and 3 cyclotrons. the process of purchasing 15 PET CT is underway. • Trainings: international professional organizations provide opportunities for to participate in conferences, trainings, workshops. Leaders in the field of RT in Ukraine create Ukrainian-language training courses for their colleagues. • international projects: IAEA project “Development of HR Competencies in Ukraine in Radiation Oncology and Imaging” and EU-UA Nuclear Research and Education Capacity Building project related to improving training programs for medical physicists. • volunteer activity: the Help Ukraine Group, a volunteer group formed after the full-scale invasion, participate in a lot of projects, providing ideas, consultations about current situation and needs, are project authors and active participants in their implementation. Conclusion: The invasion has profoundly disrupted RT services in Ukraine, highlighting the need for urgent international support through equipment donations, training, and infrastructure upgrades. Collaborative efforts have dramatically changed the expected negative impact of a long-term war on RT to a development that was not observed before even in peacetime. This could be an example of how uniting around a problem makes a difference.
