Oxygen Depletion in Cells Irradiated at Ultra-high Dose-rates and at Conventional Dose-rates
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1974Irradiation at conventional dose-rates of an oxygen-equilibrated bacterial cell suspension in a sealed vessel produces breaking survival curves similar to those observed for cells irradiated as a t...

Human enteroids as a tool to study conventional and ultra-high dose rate radiation
Integrative Biology, 2023Abstract Radiation therapy, one of the most effective therapies to treat cancer, is highly toxic to healthy tissue. The delivery of radiation at ultra-high dose rates, FLASH radiation therapy (FLASH), has been shown to maintain therapeutic anti-tumor efficacy while sparing normal tissues compared to conventional dose rate irradiation ...

Medical Physics
AbstractBackgroundUltra high dose rate (UHDR) radiotherapy using ridge filter is a new treatment modality known as conformal FLASH that, when optimized for dose, dose rate (DR), and linear energy transfer (LET), has the potential to reduce damage to healthy tissue without sacrificing tumor killing efficacy via the FLASH effect.PurposeClinical ...

Survival of mammalian cells exposed to X rays at ultra-high dose-rates
The British Journal of Radiology, 1969Abstract X irradiation delivered in single, nanosecond-length pulses, so that the instantaneous dose-rate exceeded 7 × 1010 rads/second, was less effective in abolishing the subsequent reproductive capacity of HeLa and Chinese hamster cells in vitro than was irradiation delivered at lower dose-rates.

Toxicity of hadrontherapy at ultra-high dose rate
Toxicité de la hadronthérapie à ultra-haut débit de dose La radiothérapie à Ultra-Haut Débit de Dose (RT-UHDD), de l’ordre du Gray/msec, est une technique prometteuse pour réduire la toxicité aux tissus sains. Par ailleurs, la balistique des hadrons (protons/ions d'hélium) permet un meilleur ciblage des tumeurs, limitant la dose ...openaire +1 more source
