APPENDIX
MEASUREMENTS OF INDIVIDUAL PARTICLES
The size, shape, color (when determined) and corrected gamma activity
of the particles investigated are listed in the following tables. In
regard to particle shape, symbols S, I and D represent spheroidal, irregular, and dendrite~-like respectively. Particle designation refers to the
collecting tray and the sequential order in which the particle was studied.
Discontinuities in sequential order indicate either labeling errors or ana
lytical errors compelling the elimination of certain particles.
