Roof washdown studies were conducted on typical roofing surfaces and a basic washdown system was developed. An analysis of the roof washdown countermeasure showed it to be valuable only on buildings with heavily shielded walls or where the occupants are confined to the center of a building with a very large floor area. A complete recirculating roof washdown system will cost only 45 of the cost of a concrete roof that would give a similar reduction of 98 in the roof contribution to gamma radiation exposure inside the structure.
