TABLE B.23
OBSERVED DOGHOUSE DECAY RATES OF FALLOUT AND CLOUD SAMPLES
Fallout samples listed are total undisturbed OCC trays, counted with aluminum covers in place on the floor of the
counter, ~36 inches from a 1 inch Nal(T1) crystal.
The standard cloud samples are essentially point sources of
filter paper in lusteroid tubes, placed in a clean OCC tray, and similarly covered and counted. The extended
sources, or fallout samples, have been corrected to a point source equivalent by increasing the observed counting
rate by 7 percent (Reference 66). Their fission contents appear under Total Fissions in Table B.12.
