THE BIOELECTRICAL RESPONSE OF THE INSECT EYE TO BETA RADIATION

摘要

Moths of the family Noctuidae were used to determine the bio-electric responses of the compound eye to ionizing radiation. It was found that 0-radiation can induce a bioelectric reaction in the compound eye of the insect. The electroretinographic pattern in indistinguishable from that produced in response to a light stimulus. The flicker-fusion frequency threshold is also similar for the two stimuli. However, a difference exists between light and 3-radiation in the time course of the dark adaptation process. It could be demonstrated that the disparity is dependent upon the interaction of visual pigment with the light, stimulus;An electroretinogram response was elicited by a P-radiation exposure dose of less than one milliroentgen at the radiation dose rate of 20mr/second.
