Specimens of candidate fluorescent particles from each of six lots manufactured by United States Radium Corporation for the U. S. Publc Health Service Division of Air Pollution were submitted for physical analysis to determine for each lot specimen (1) characteristic particles-per-gram and mass-mean-diameter, (2) particle size distribution in approximately one-micron diameter intervals, and (3) certain additional qualitative characteristics pertinent to the suitability of these materials as FP air tracers. Results are included in tabular form.
