Four-inch cubes of commercial shielding window glasses were tested for susceptibility to fracture by electrical discharge following intense gamma irradiation. All glasses tested were easily discharged by an impact probe after an exposure of 1 to 10 megaroentgens. The negative charge collected by the probe circuit increased with exposure rate and decreased with the irradiation temperature. This collected charge is thought to be an approximate measure of the internal charge acquired by the giass cube. A serious effect for shielding windows, is that a small dendritic fracture, once formed, will continue to grow with subsequent exposure. Recommendations are made concerning the design of windows to reduce their susceptibility to fracture. (auth)
