Ultrahigh dose-rate protons reduce hydrogen peroxide yield in water
Hydrogen peroxide production decreased as proton dose rate increased, with Geant4-DNA simulations reproducing the oxygen-dependent experimental trend.

Single-fraction proton treatment produced pain responses without grade 2 or higher related toxicity in 10 patients with thoracic bone metastases.
In mice, ultrahigh dose-rate X-rays caused less early testicular damage than conventional irradiation, with protection linked to ferroptosis suppression.
Normal-tissue sparing with ultrahigh dose-rate radiotherapy remains conditional and cannot replace conformal dosimetry, organ-at-risk constraints, or rigorous quality assurance.
FLASH radiotherapy preserved hepatic structure and metabolic homeostasis while maintaining tumor control in a preclinical breast cancer model.
