Abstract : For neutrons normally incident on a shelter doorway, the presence of an aluminum blast door of reasonable thickness will not greatly vary the hazard inside the shelter from that which would result if no door were present. When the neutrons are incident at such an angle that the direct beam would not penetrate appreciably into the shelter, the presence of an aluminum door would indeed create a greater radiation field within the shelter. However, the aluminum door would create no greater hazard than a steel door of comparable strength; on the contrary the former would probably create less hazard.
