Abstract : An improved radiation protection louver system is described which comprises a movable louver panel hinged to a rotatable shaft through a thermally sensitive closure hinge member comprising a martensitic structure alloy exhibiting the characteristic of changing its shape from an intermediate configuration to a predetermined configuration in response to exposure to high intensity radiation. Motor drive means is included to reshape the hinge to the desired intermediate configuration following a temperature excursion effecting change of configuration. (Author)
