Mr. Robert L. Corsbie The proposed Civil Defense tests for 1957 includes about forty scientific projects. 1957 CIVIL DEFENSE TESTS These have been proposed in addition to the FCDA and the AEC, by the Departments of Defense, Health Education and Welfare, Commerce and Agriculture; the General Service Administration, the State Civil Defense Administrations,U. S. Industry, NATO member nations, France, West Germany, and Sweden (a non-NATO nation). (At this point Mr. Corsbie's description of the proposed tests became classified and are immaterial to these Minutes.) Several projects involve radiation dosimetry for human exposures, some to develop information on ecological aspects of fallout, countermeasures, and decontamination aspects and procedures and others to improve fallout predictions as related to meteorology. The development and testing of shelters of various construction is also planned. Plans have been made for preliminary aerial surveys between October 15 and November 1, 1956 for the purpose of determining the present levels as well as to familiarize the crew with the terrain and give experience to FCDA personnel. MR. CORSBIE told of the vigorous attempt to declassify civil defense documents. MR. CORSBIE then introduced the subject of the civil defense aspects of AEC installations. He described a general review being made by his group consisting of a questionnaire to operations managers and visits to the larger installations. CIVIL DEFENSE - AEC INSTALLATIONS Six of the ten Operations Offices have already been visited as well as Los Alamos and Berkeley. After the remaining four large installations are visited, an attempt will be made to prepare an interim report by November 1. MR. CORSBIE then described briefly Operation Alert 1956 where AEC installations responded to a wide variety of degrees. Particular mention was made of the excellent analysis made by Berkeley. The results showed that 50 percent of the personnel would have been fatalities solely from fallout. - 25 -
