Airborne debris from nuclear weapons tests has been collected since 1955 and examined for radioactivity. The debris was collected on glass-fiber paper with a sampling device carried by an aircraft at altitudes up to about 10 miles. Part of the filter paper is used for spectrometric determination of a number of gamma -emitting nuclides, from which an age determination can be made. The remainder of the filter is radioautographed on photographic film. From the radioautograms it is possible to determine the activity of the individual particles and to locate their positions on the filter. Measurements were made of the size of radioactive particles. The particles were examined microscopically. Data are presented graphically on the activity of 950 particles of various sizes. Characteristics are described for debris from the Soviet test series of Sept. and Oct. 1959. (C.H.)
