Lesson 1/Learning Event 2
Proper functioning of the contamination information collection effort requires that all units submit
certain automatic monitoring reports. These reports provide the minimum essential monitoring
information for warning, survey planning, and hazard evaluation purposes. Automatic reports are
submitted through command or intelligence channels to the Tactical Operations Center (TOC) of the
major command having area responsibility for the location in which the monitoring information was
For example, a corps unit located in a division area would submit monitoring reports to division.
Intermediate headquarters screen these reports and forward only those which are necessary to describe
the radiological contamination hazard in areas of responsibility.
Contact Report. Warning units of approaching fallout or of previously undetected contamination is a
primary step in avoiding casualties or combat ineffectiveness from radiation or chemical hazards.
Fallout warning or contaminated area warning to be meaningful, must be based upon information from
units that initially contact the hazard. A knowledge of the area is necessary for survey control, traffic
control, and other activities. All units will submit contact reports with IMMEDIATE precedence
whenever an initial ground dose rate of 1 cGy(rad)/hr or more is detected in an area. These reports will
provide the basis for issuing fallout and contaminated area warnings throughout the major command.
Intermediate headquarters will screen and evaluate these reports and reduce the precedence if the hazard
has already been detected and reported.
Peak Radiological Dose-Rate Report.
In the case
of radiological fallout, the dose
rate will steadily
until it reaches a peak and then will decrease as the contamination decays. (Caution should be used
when complying with this peak dose-rate criterion. In some cases, the dose rate may fluctuate for a
short time before beginning a constant decrease.) Units will report this peak dose-rate. In the event the
survey meter goes off scale, the unit will port when the survey meter comes back on scale after peaking.
(Monitors should not necessarily remain in the contaminated area waiting for the meter to come back on
scale. If the monitor is in the area when the meter comes back on scale, however, this time should be
Special Reports. SOP's or other standing instructions may establish special automatic reports. These
special reports are for evaluation by the TOC of the contamination hazard for the purpose of inviting
command attention to areas of serious concern.
