hi tection is being considered for those facilities which may remain on the shot islands and still be re-used for another experiment. The mobility of mechan- ical equipment enables the removal of such equipment to be accomplished in the last few days prior to a shot, with a minimum accompanying use of heavy construction=type equipment. Removed equipment could be either loaded on barges which may then be accumulated at mooring adjacent to each shot island, and towed in a chain to Parry Island for further disposition or removed in "M" boats by decrements; hence it is not believed necessary to maintain a large fleet of "M" boats for this purpose alone. Demobilization. As part of the demobilization following the testing period, the following functions are proposed to be performed as soon as radiological conditions permit: salvage, storage, a system of maintenance of permanent utilities and structures, and a protection of structures and utilities. Such structures as are considered undesirable to leave in place from the standpoint of security would be removed, demolished or obliterated, as directed. The Gamma Stations, being of a special aggregate subject to oxi- dation, would be wire-brushed and scrubbed to clean the mmface from oxides and coated with an asphalt base coating, which should then be covered with sand or other sun protection. The metal parts of permanent structures on shot islands should be coated with long-lasting preservatives such as cosmoline. Cable landings should be reposted with warning signs. It is also sug- gested that areas of intense radio activity be fenced and marked. On Parry Island, warehousing of materials to be left at Proving Ground should be ac-= complished; those which are subject to deterioration should be stored in dehumidified warehouse, and arrangement for shipment back to the Zone of Interior of other materials should be made.
