The injury expectation with non-instantaneous delivery of
radiation cannot be schematically quantitated with the data available.
As total dosage is protracted, there undoubtedly will be a decrease in
the incidence of the acute toxic phase mown as "radiation sickness".
However, for radiation delivered over relatively short periods of time,
such as one or two days, it probably is safe to assume that the hemorrhagic and systemic infection problems will remain almost the same as
for instantaneous dosages:
Various semi-quantitative statements are
available, but these are based on opinion and no accurate data are
available for critical study.
The statements given by McLean in the
Military Surgeon, which are substantially the same as those given by
the Radiological Warfare pane22/ ere summarized here.
This is done to
provide a "feel" for the problem.
