Outside the Predicted Area.
Outside the predicted area, exposed, unprotected personnel may receive a
total dose that does not reach 50 centigrays in the first day (24 hours)
after actual arrival of fallout.
The total dose for an infinite time of
stay outside the predicted area should not reach 150 centigrams. Therefore,
outside the predicted area, no serious disruption of military operations is
expected to occur if personnel have not previously been exposed to nuclear
radiation. Appreciable previous exposure should be considered. In either
case, periodic monitoring coupled with routine radiological defense measures
will normally provide adequate protection.
The predicted zones of fallout are larger than the actual ground area that
will be covered by fallout.
These zones represent areas of hazard,
somewhere within which radioactive particles are predicted to fall. Because
of uncertainties of weather and nuclear burst input data, the precise
locations of fallout within the zones cannot be reliably predicted, but must
be ascertained by monitoring and survey after fallout has settled.
zones, therefore, have been developed so that there is reasonably high
assurance that the expected fallout will not occur outside them.
represent an expected hazard area that can be quickly predicted immediately
after receipt of actual or planned nuclear burst information.
absolute boundaries for the occurrence of fallout. It is emphasized that as
these predicted zones are approached from the outside, the likelihood of
encountering hazardous fallout will increase as will the dose rate.
Therefore, units should not normally be relocated based upon predicted
fallout areas but, rather, upon actual radiological monitoring and survey
PART B - PREPARE A DETAILED FALLOUT PREDICTION
All NBC weapons have an inherent residual effect that presents a hazard to
the forces engaged.
Nuclear bursts create local contamination of an area
around ground zero and may produce radioactive fallout which can contaminate
thousands of square kilometers.
weapons are a necessary consideration in preplanning operations in which
friendly forces may be required to occupy contaminated terrain.
