The analysis by Mr. Lee dealt with the effects of drinking filtered
but otherwise unprocessed surface-source waters that were contaminated by fallout deposited directly into the surface sources.

Two hypo-
first, a heavy, mixed attack against city
and counterforce targets with a total yield of 12,000 MT; and second, a
city-avoidance, medium counterforce attack with a total yield of 7,000 MT.
In both attacks the weapons were assumed to be surface burst, and the
yields were assumed to be 50% from fission and 50% from fusion.
