Food and water contamination in period immediately following molear
explosion,
(AEC-WFBale, 12/13/50).
These are about 25 times the
ordinary peace time tolerancese For emergency instruments, make
the scale cover 1/25 to 4 times these values, if the range of the
meter is a hundred-fold.(verbal agreement Bale-Evans-Failla,
