radiation. All nuclear radiation, even in small doses, has some harmful effect on the body and should be
avoided whenever it is possible to do so without interfering with military operations.
1-2. Response Factors. The response of an individual to nuclear radiation depends upon several
The total dose accumulated from previous radiation exposure.
The period of time over which the doses were received.
The recuperation time between exposures.
The physical condition and age of the individual.
The presence of any additional injuries.
a. It is impossible to predict the effect of a specific dose of radiation on any one individual;
however, the average effect on a large group may be predicted with enough accuracy for military
purposes. The expected response in groups of personnel exposed to nuclear radiation is shown in Table

*Symptoms include diarrhea, "dry heaving," nausea, lethargy, depression, and mental disorientation.
At lower dose levels incapacitation is a simple slowing down of the rate of performance due to loss
of physical mobility and/or mental disorientation.
b. Control of radiation exposure may affect operations by influencing the commander's decisions
in the selection of a course of action and the units to be employed in a given operation. Continuous
evaluation of unit radiation exposure levels is necessary to assist in making these decisions.
1-3. Operational Exposure Guidance. Radiation exposure should
to the maximum extent
possible consistent with the mission. On occasion, this may tend to restrict operations; but if exposure
control is ignored, the results could be disastrous. The establishment and use of OEG will aid the
commander in keeping radiation exposure at a minimum and assist in the accomplishment of the assigned
