Rabbits were exposed to fast neutrons in doses of 20 to 400 rad. An electrical ophthalmoscope and biomicroscopy were used for examining the lens. After 15 months the structure of the lens was severely impaired with fewer nuclear elements in the region of the germinative zone some of which were displaced to the posterior and some to the anterior cortex. The threshold dose for inducing cataract was about 100 rad. Six to 7 months after delivery of this dose clinically demonstrable opacities appeared in the lens which progressed appreciably and affected the function of the eye. Data showed that the rabbit lens is four times more sensitive to radiation than the human lens. (HLW)
