Ametek Detective-200

Mobile Radiation Detection - Ruggedized, Ultra-High Sensitivity, Transportable HPGe Radionuclide Identification System

ORTEC’s line of gamma and neutron detection instruments are simple to use, designed for nuclear search and emergency response. Whether you need to search for elevated sources of radioactivity or resolve whether an alarm is the result of cosmic background radiation, industrial sources or special nuclear material, the company’s top-of-the-line detection systems will give you a correct answer every time. The most common approach to detecting RDD or IND devices is through their gamma-ray signatures.
The resolution advantages of HPGe over NaI (approximately 40 times better resolution than NaI) more than offset the difference in crystal size. The Detective-200 HPGe systems from ORTEC offer much greater detection probability, better standoff detection and better detection of shielded or masked sources. This is especially true for searching for SNM threats in an urban environment where backgrounds are constantly changing as the detection system moves.
Due to their modularity, the Detective-200s can be deployed in a variety of applications. They can monitor choke points (such as vehicles or pedestrians), long range standoff detection (such as long count times for objects more than 100 meters away), mobile search systems and maritime search systems.
The Individual Detective-200 can also be removed from the vehicle and used at choke points, such as bridges or tunnels, or even as a portal at special events.


  • Large Area HPGe Detector (~5675 sq mm) gives definitive identification of illicit nuclear material (SNM) in seconds.
  • 10 times faster to identify HEU than a “conventional” NaI based identifier.
  • Built-in removable 120 degree collimator reduces background interference in field of view.
  • IP67 waterproof, dust proof and shock resistant packaging
