APPENDIX C
PARTICLE DATA AND CHARACTERISTICS, SHOT KOA

C.1

Size Distribution, Fall Rate and Specific Activity Data
Fall rate distribution data, particle size data and specific activity-

fall rate data are presented in graphical form, in Figures C.1 through C. 13,
for the cloud and fallout samples listed in Table C.1.

Samples 500, 502 and

977 from the cloud were separated into coarse and fine fractions with the

Bahco centrifuge before determination of the distribution curves.

The»

boundary between the centrifuge fractions is as given in Appendix B. No
fall rate work was done on samples taken from the cloud at times later
than four hours due to the small quantity of material collected.
