Observations of visual sensations produced by Cerenkov radiation from high-energy electrons.

摘要: Abstract Ten cancer patients whose eyes were therapeutically irradiated with 6–18 MeV electrons reported visual light sensations. Nine seeing blue and one white light. Controls no Additionally, tests ruled out the x-ray contamination of electron beam as being important. The photon yield due to Cerenkov radiation produced by radium its daughters for both gamma rays was calculated; it found account a turn-of-the-century human observation “radium” phosphene. We conclude that dominant mechanism this phosphene is radiation, primarily from betas. From our own patient data, based on color seen production rates, we high-energy are an example particle induced
