Moths of the family Noctuidae were used to determine the bioelectric responses of the compound eye to ionizing radiation. It was found that beta-radiation can induce a bioelectric reaction in the compound eye of the insect. The electroretinographic pattern is 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 beta-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 beta-radiation exposure dose of less than one milliroentgen at the radiation dose rate of 20mr/second. (Author).
