Fig. 35 — Fallout Conditions Following Attack on 5 Aug 55
A random sample of 36 days (3 days per month) was selected from available upper
wind fallout (uF) readings.
These data were used to select appropriate fallout contours
and bearings as described in the section on deaths from fallout.
Ten-Mt ground bursts
were exploded on all the rcpa-designated critical targets within 300 miles of the Washington
target.
The weapon was exploded over the center of population in each target except
Washington and Baltimore, where expected Gz for a cep of 4000 m were used,
The targets
and the numberof weapons assigned (roughly on a population basis) are given in Table 10.
The area shown in Fig. 36 was then examined for the cumulative 2-day radiation dose
received on each of the 36 days of the attack. Contour lines were drawn for radiation conditions that existed 100 percent of the time, 70 percent of the time, and 50 percent of the
