Contraband Detector PM2030 of nondestructive examination is a portable security instrument that detects hidden items (drugs, explosives, weapons, currency, etc.) within the closed cavities of transport vehicles, freight containers and other objects.
The instrument can be applied in impracticable for examination condition, where stationary examination equipment can not be used. The PM2030 indicates the presence of sealed radioactive material in any closed volumes (freight containers, automobile tires, doors, bumpers, fuel tanks, train carriages, etc).
PM2030 indicates the identified objects and forms the library. Due to modular design of the device and telescopic extension pole, hard-to-reach places and large objects can be scanned. For work in noisy places, vibration alarm from the handle is provided.
PM2030 can be applied in Customs and Border Patrol, Police, Special Services, Security Offices.

Operation Principle
The Contraband Detector features the plastic case and consists of two units: display and control unit and scan unit with rubber handle.
In operation mode the detector emits a beam of gamma radiation into the object being inspected and measures the backscatter. PM2030 features the build–in radiation source 133Ba with activity 320-370 kBq. The source is housed within the lead safety container-collimator of the scan unit.
The intensity of the backscatter depends on the object features (its density and size). The device is moved along the surface of the object. The change in the density of the object is displayed on LCD and accompanied with light, sound and vibration alarms. The frequency of alarm repetition depends on the size and density of the detected cavity of items.
The lead container-collimator provides the necessary narrow zone of the object radiation during examination and complete protection of the operator from gamma radiation.
Scanning Mode
The Contraband Detector in the SURVEY mode detects (detection probability 0.5, confidence probability 0.95, when moving the instrument with no more than 5 сm/s speed) the objects sealed behind a steel partition of 1 mm thick or behind a wooden partition of 20 mm thick:
- aluminium 30х30х30 mm
- polyethylene 70х70х20 mm
- steel 30х30х10 mm
The instrument in the SURVEY mode in a static position detects the objects sealed behind a wooden or plastic partition of no more than 20 mm thick with 0.5 probability, as well as defines the metals group or plastic. The defined material name (metal group or plastic) is displayed on the LCD. The objects dimensions should be no more than:
- polyethylene block 70х70х20 mm
- steel block 70х70х5 mm
- sheet of silver group 70х70х0.5 mm
- sheet of lanthanum group 70х70х0.5 mm
- sheet of tungsten group 70х70х0.5 mm
- sheet of gold group 70х70х0.5 mm
- sheet of lead group 70х70х5 mm
