Principle of OperationThe Model K910B Contraband Detector indicates the difference in density between contraband (drugs, explosives, weapons, currency, etc.) and the object in which the contraband is hidden… for example, an “empty” tire filled with air as opposed to an “illegal” tire filled with drugs or an “empty” cross member in a freight container stuffed with contraband.
Buster directs a beam of energy into the object being inspected. A filled space reflects back more energy that an empty space. As Buster is moved across the surface of the object, the measurement is displayed on a digital LCD, and an alarm sounds if the density changes.
Easy to Use
Using Buster is simple. Hold Buster on the surface of an object that is known to be clean (e.g. on a package that has been physically inspect out of a group of packages). Then squeeze the trigger and turn Buster on. This opens a shutter in the shield to direct a beam of gamma rays through the article being inspected. A two second “normalizing” period begins in which the reflected energy is averaged, digitized, and displayed on the LCD. The normalized reading is set into Buster’s memory as the “zero” or baseline reading, against which subsequent densities are compared.
As Buster is swept across the surface of the (suspected) object and a change of density is detected, a “beep” will sound as the density changes. At the same time, the LCD display updates every half second to show higher numbers as the density increases or lower numbers as the density decreases.
Thus, through sight and sound, Buster identifies changes in density. For example, when passed over a wall it will locate the studs, or in like manner, it will discover contraband hidden in bodies of vehicles and in fuselages and wings of aircraft. It will also indicate concealed spaces in objects that are supposed to be solid, thus identifying secret compartments.
Looks Beneath the Surface
Buster’s directed beam of gamma rays will penetrate the surface of an object. It can “see” through wood, metal, textiles, plastic, etc. Since every material has a specific density, unexpected changes become obvious. The gamma rays cause no damage to the objects being inspected.
Typical Inspection Procedures
Tires. Compare readings on a known “clean” tire to readings on a “suspect” tire. High display values indicate something is in the tire.
Car Doors. Normalize Buster on center of door with window up. Changing display and alarm will locate contraband behind panels.
Fuel Tanks. Normalize Buster on the underside of the tank. Sweep across underside of tank and observe changes in display or alarm. Buster will indicate fuel level on side of tank.
Walls and Lined Containers. Normalize Buster on the wall. Move Buster horizontally over the wall noting changes in display and alarm as structural members are detected. Investigate unaccountable changes from normal structural pattern.
Aircraft. Buster is excellent on aircraft. Use in same manner as on car doors and on walls.
Trucks, Caravans, Buses,Trains, etc. Normalize Buster on objects to be inspected: tires, fuel tanks, water tanks, wall mattresses, compartments, ceilings, etc. Move Buster over the object and investigate unaccountable changes in readings as indicated by the display and the alarm.
Identical Packages, Flower Shipments, etc. Physically inspect one package, then normalize Buster on this package. Move Buster over remaining packages and investigate unaccountable changes in readings which deviate from the original trial package. This method can be used to check seats on a bus, for example.
Boats and Ships. Test bulkheads, cabin insulation, decks and overheads, fuel tanks and storage areas for false compartments.
Freight Containers. Check walls for hidden panels, examine cross members which may have contraband hidden in them.
