ABSTRACT OF THE IVENTION Significant, life-saving protection from airborne, radio- active (fallout) particles due to nuclear explosions, nuclear reactor accidents, and other releases of radioactive particulate is provided by a double-wall tent structure quickly erectable over a central trench hole. The tent structure includes tight- ly woven, rip-resistant fabric panels supported by tensile rods or wands, a tub floor extending into and lining a central trench or hole, and an exterior, light-reflecting, metalized, semi- transparent disposable membrane. The bottom circumferential edge of the outer membrane extends into a shallow trench or-ditch, excavated around the perimeter of the inner tent structure. Dust particles settling onto the smooth exterior surface of the mem- brane slide off and are captured in the shallow ditch, thus minimizing direct or indirect radiation into the central trench or hole and its occupants. The perimeter of the outer membrane contains pockets for the storage of potable water and for anchor- ing of the outer membrane. The tub floor lining extending below the ground surface includes sealable pockets suitable for the storage of refuse and human waste during occupancy. Also de- scribed is a light-weight single membrane, plastic, portable tent, suitable for low-cost mass production.
