Description
Summary:The sensitivity of the chick embryo to radiation hazard was investigated. Retinal anomalies were chosen for subjects, because it was revealed that the central nervous system including the retina showed the highest sensitivity against radiation. Various degree of abnormalities from the discontinuities of the outer nuclear layer to the severe rosette formations were observed, and the dose-effect relationship in different irradiation stages were investigated. It was concluded that the most sensitive stage is 6 days old embryo, and it's minimal effective dose is 350 r. It was observed also that the situation of retinal anomaly in the eye globe depends on the embryonic stages irradiated.
