For persons living near or in potential blast areas, we recommend a dogleg type entrance. This creates several 90 degree turns that gamma radiation must negotiate before striking shelter occupants. In addition, 50 lb. bags of grain and 8 gal. water containers can be stacked in the horizontal run for effective shielding against prompt neutrons, present within 7,000 feet of surface zero of ground burst nuclear weapons.
