Description

Proton irradiation of the rabbit's eye resulted in injuries of the same nature as those from other ionizing radiations, yet the evolution of the pathological processes thus induced were different since the injuries became stabilized at a precise stage of cataractogenesis. The localization of the radiosensitive sites was verified and a lack of LET effect was noticed. Since mammalian lens are not very different from one another, the results can be extrapolated to man. The hazards to man arising from accidental exposures exist but they are very low

Abstract (French)

Si les irradiations par des protons de l'oeil du lapin induisent des lesions de meme nature que celles engendrees par d'autres rayonnements ionisants, on montre que l'evolution des processus pathogeniques induits de la sorte est differente puisque les lesions se stabilisent a un stade bien defini du processus cataractogene. On confirme egalement la localisation des sites radiosensibles et on met en evidence, par cette technique, l'absence d'effet de TEL. Etant donne que les cristallins des differents vertebres ne se differencient guere les uns des autres, on pense que les resultats sont extrapolables a l'homme. Les risques engendres a ce dernier par une exposition accidentelle existent donc, mais sont toutefois tres faibles
