Contraband Detector PM1401T

Zoom

Small hand-held contraband detector for search of concealed contraband items, such as explosives, drugs, guns etc., in the tires, walls and hollows.

Recommended for use by Customs Officers, Border Patrol and Law Enforcement Agencies.

where

Polimaster’s PM1401T contraband detector is a light-weight portable device which can detect the presence of the hidden materials in the concealed areas. The instrument includes high-sensitive personal radiation detector PM1401MA on the basis of Csl(TI) scintillator.

Operation Principle

The operation of the instrument is based on detecting of backscattered radiation from a built-in 133Ba source while moving the PM1401T across the investigated object. The backscattered radiation is detected by a highly sensitive CsI scintillation detector.

The backscattering from the filled hollow space (such as contraband drug or guns in the car tires) reflects the gamma rays differently from non-filled space (such as air-filled tire) or solid material (such as piece of thick rubber). The PM1401T can easily detect the density changes and alert of the presence of contraband through visual, audible and vibration alarms.

In spite of the fact that the PM1401T has a built-in radioactive source, there is no danger to an operator. The source is properly shielded and gamma rays are emitted only in the direction of the inspected object.

PM1401T is also able to detect gamma radiation from radioactive and nuclear materials and can be used as an additional Personal Radiation Detector (PRD) at customs checkpoints for preventing illicit trafficking of the radioactive and nuclear materials.
