In recent years, the FLASH effect, which has been reported to reduce normal tissue toxicity while maintaining tumor control through ultra-high dose-rate irradiation, has attracted considerable attention in radiation therapy. To elucidate the underlying mechanisms of the FLASH effect, it is essential not only to establish ultra-high dose-rate irradiation fields but also to develop dose evaluation methods applicable under such irradiation conditions. In this study, irradiation experiments using radiochromic films were conducted with the electron linear accelerator (KURNS-LINAC) at the Kyoto University Research Reactor Institute, and the characteristics of the films under ultra-high dose-rate irradiation conditions were evaluated.
