Report No. TO-B 67-20 on ZAage Analysis
WORK PROGRAM: Infectious Development Experiment: Consisting Of Counting
The Silver Halide Crystals (Singles and In Clumps) In
Exposed Undeveloped Sub-Mono Grain 'Layer Model Emulsion
Number N-2-0056.
'MORE SPECIFICALLY
1. Photographed undeveloped film samples, from emulsion N-2-0056,
under high magnification (1700x) and took a sufficiently large number of
frames to encompass 9560 grains.
Micrographs were printed high contrast in the positive form on 8 x 10
inches D.W. Matt Photo Paper.
2. Determined how many single isolated grains there are and how many
grains are situated in clumps by actually counting:
A. average total grains in all the eleved 8 x 10 photo prints
(870 grains)
B. Average isolated single grains in all the eleven frames.
(121 single grains)
C. Subtracted average total of single isolated grains from
average total of all grains to yield total of grains in clumps.
(749 in clumps)
D. Calculate average isolated singles as a percentage of average
total grains counted in each 8 x 10 print,
121 grains or 14% average isolated single grains .counted in a given
area, (8" x 10" Photo print at 1700X) .
