>"It delivers a dose of radiation that’s over 300 times higher than traditional radiation therapy in just a fraction of a second. This induces something called the “FLASH effect” — a not-entirely-understood phenomenon in which the radiation still attacks the tumor, but doesn’t harm surrounding tissue."
