Lesson 2/Learning Event 4
Procedures for using point technique. Procedures for using the point technique vary according to the
situation:
When the situation permits, the aircraft lands near the point of interest and the monitor
dismounts, proceeds to the selected point and takes the reading by using normal ground
monitoring procedures.
When the situation does not permit use of the above procedure, an estimation of the ground
dose rate may be made by use of an air-ground correlation factor and an aerial dose-rate
reading.
Simplified Aerial Survey
Battlefield conditions or the operational situation may preclude the preparation of the detailed
radiological contamination overlay, and a simplified radiological contamination overlay may then be
needed to satisfy the commander's requirements. A simplified aerial survey will normally be required to
complete the overlays.
information for evaluating the contamination hazard. The minimum essential information is that
required to determine the outer limits of the area of militarily significant contamination, a few dose rates
in the most heavily contaminated parts of the area, and dose rates at points of operational interest. The
simplified survey must be accomplished and the information provided to the control party as soon as
possible after contamination is on the ground.
Techniques. The techniques of conducting simplified aerial surveys are the same as for detailed aerial
surveys with the following exceptions:
The simplified survey requires considerably less detail than the detailed survey.
The simplified survey may cover only those parts of the contaminated area which are of
immediate operational concern.
The control party preplans only the general area in which the simplified survey will be
conducted. After arriving over the area, the survey party selects the check points, routes, and
course legs.
A debriefing is held by the control party after this survey is performed.
