Note: Chemical constitution of the soil, and particle size dis- trioution of the soil before the test, erious locations downwind for about 50 miles. Chemical composition and physical constitution -- how much "plating" occurs? Concentration in the air. Analysis procedures should be previously developed to a point which will permit the above data to be adequately evaluated within a period of 7-10 days. Item 1. b. will be the responsibility of AFOAT-1. Item 9 and 10 are to be primarily the responsibility of the Operations Group, Other items will be the resvonsibility of the Division of Biclogy and Medicine until otherwise assigned. Recommendations It is the unanimous agreement of the Committee that a test involv- ing the explosion of 41.25 kiloton Uranium 235 bomb, under the con- ditions stated in the body of tho report, can be carried out without undue hazard. Thc Committee recommends that the test be made. *” | DO® ARCHIVES *
