Explosive detector

The perimeter or extent of the search must be determined initially.  If the 1st sweep is to be conducted by aircraft or helicopter the search method is the same as that for the outside of a building but in this case the accuracy will be less;  an area will be defined though.  If the search is to be conducted from the ground the following procedures must be followed.

Task List

1                    Walk the perimeter of the area and either make your own drawing or preferably use a map.  The reason to walk the perimeter is to see how it can be subdivided into roughly 50m sq areas and mark the possible hide or drop points.

2                    Subdivide the area and split the work between however many teams you have available to conduct the search.

3                    The subdivided areas are searched marking on all the readings but being aware of where the other teams may be.

4                    An additional unit can be used to check specifically the hide and drop off areas at the same time as the open areas.  Again be aware of the other units.

5                    Use marker flags to define the direction of each indication is available.

6                    Check to see if the readings continue outside the area and take note.

7                    Remember the substance could be under the ground or in the vegetation.

8                    Once the area has been searched and substance found check again to make nothing has been missed.  The one you found could be a decoy!

9                    Beware that any subsequent readings may be residue but sometimes the presence of one sample can mask the presence of another if close.

The immediate area around the substance produces a high energy field which is the same as the substance, therefore making it difficult for the Mole to indicate its exact position.  When you are very close to the substance it can be extremely difficult to pinpoint it.  The effect can be likend to that of to like magnetic poles repelling each other when very close.  This is why we should be confident of our readings which are taken at a distance of at least 2 meters.
