The relationships expressed in this equation were used to develop figures
19 and 20.
Figure 19 enables one to determine, from a knowledge of the H+1
hour dose rate, the total integrated dose received by an individual in
48 hours for any particular time of entry or any particular time of
arrival of fall-out.
Figure 20 shows contour lines for radiation received up to
H+48 hours, correcting for time of fall-out and assuming a 15 knot wind.
Radiation Injury Expectation.
When exposed to sufficient radi-
ation, personnel will show evidence of radiation injury varying from the
acute radiation syndrome of nausea, vomiting, malaise, etc., to hemorrhagic phenomena end infection, with all the attendant clinical findings.
Table 6 summarizes, essentially on the basis of the Hiroshima and
Nagasaki experience, the effects of various instantaneous radiation
doses.
