Аннотация:This paper presents an overview of current experiments and calculations on a new methodof radiation therapy, that is, flash radiotherapy. This method involves an increase of the average dose rate to 40 Gy/s and higher, thus providing better protection of healthy tissue compared to conventionalradiotherapy. This article analyzes the results of recent experiments on flash radiotherapy with proton beams, electrons, and bremsstrahlung radiation. It also describes technical problems of achieving high dose rates and the possible ways to solve them. Flash radiotherapy with different particles appears to be promising and probably will be applied in the future. However, there are still many issues that should be solved before applying it for medical purposes.
