Abstract: FLASH radiotherapy is moving from animal experiments to clinical trials. However, the research on radiation shielding of FLASH radiotherapy rooms has been still in the initial stage. This paper analyses the structural characteristics of the beam pulse of FLASH radiotherapy devices of different technical routes, and discusses the radiation shielding challenges facing the radiotherapy room from FLASH radiotherapy technology based on the current protection standards for the radiotherapy room at home and abroad. The purpose is to provide input to the research on radiation protection of FLASH radiotherapy and to promote the clinical development of FLASH radiotherapy.
