All radiological safety operations for Operation CASTLE (RESTRICTED..
$I) » Will be considered as routine and will comply with permissible radiological exposures for routine work, except uspecial operations" which must
be specifically designated by Comdr, JTF SEVEN, In tactical situations the
military commander must make the decision regarding allowable exposures.
As military personnel are normally subject to only random exposures, health
hazards are at a minimum. Current DOD informtion on exposure to gamma
radiation in tactical situations is indicated below:
a.
Uniform acute (immediate) exposure of fifty (50) roentgens to
a group of Armed Forces personnel will not appreciably affect their efficiency
as a fighting unit.
\
b. Uniform acute exposure of one h
ed (100) roentgens will
produce in occasionalindividuals nausea and vomiting, but not to an extent
that will render Armed Forces personnel ineffective as fighting units.
Personnel receiving an acute radiation exposure of one hundred (100) or
more roentgens should be given a period of rest and individual evaluation
as soon as possible.
c.
Uniform acute exposure of approximatelyone hundred fifty
(150) roentgens or greater can be expected to render Armed Forces personnel
ineffective as troops within a few hours through a substantial incidence
nausea, vomiting, weakness and prostration.
Mortality produced by an
acute exposure of one hundred fifty (150) roentgens will be very low and
eventual recovery of physical fitness may be expected.
siveot Geo-Fleld Commanders should, therefore, assume that if sub“stantial numbers of their men receive acute radiation exposures
substantially above one hundred (100) roentgens there is a grave risk
that their conmands will rapidly become ineffective as fighting units.
e. Internal radiation hazards caused by entry of radioactive
substances through the mouth, through the lungs or through cuts or wounds
do not exist after an air burst. Internal hazards following a contaminating surface explosion may be avoided if ordinary precautions are
taken. Only under unusual circumstances will there be internal hazard
from residual contamination. This eliminates the necessity for masking
and consequent reduction of tactical efficiency.
