Brief survey of particle work relevant to the test sites

This paper presents an overview of the available data on the physical, chemical, and radiochemical properties of fallout particulates, of the methods by which both samples and data have been obtained and their limitations, and of the availability that remains mostly uncorrelated, but from which much information can be gleaned or inferred that is of interest to the NAEG program. Nevertheless, experimental characterization of particulates with special emphasis on transuranics is not only still possible but advisable
