Project Star Dust

Work which was done on Project Star Dust during the preceding contract year is reviewed. Filter samples of stratospheric radioactivity were collected using WU-2, RB-57 and RB-52 aircraft. Lower altitude collections included intensive sampling in the vicinity of extrusions of stratospheric air into the troposphere during the spring of 1963. A number of radiochemical and radiometric procedures used during Project Star Dust and developed since the issuance of the final report on Project HASP are described.
