Hand-Held Radioisotope Identifiers

Since 2004, ORTEC Detective Family Hand-Held Radioisotope Identifiers (HHRIIDS or RIIDS) have been in the front line of operations to interdict the illicit trafficking of nuclear materials worldwide, in everyday use by organizations such as:

Departments of Homeland Security
Departments of Defense
National Security Organizations
Bomb Disposal Teams
Emergency Response Teams
Customs and Border Control
Navy, Army and Air Forces



Emergency Management Teams
Civil Support Teams
Police Departments
Nuclear Safeguards Organizations
Nuclear Fuel Manufacturers
Nuclear Researchers
US NNSA second line of defense “Megaports” initiative

All Detective instruments base their superior performance on cryo-cooled ORTEC HPGe detectors coupled to unique identification algorithms developed from an original Technology Transfer License from Lawrence Livermore National Laboratory (TL-01754-03 and TL-01753-03), and improved based on actual in-field experience.

The range now includes instruments with and without neutron detectors, two choices of HPGe crystal sizes, and two packaging options: the classic Detective format and the Micro-Detective and Micro-Detective-HX which reduces weight by 40%.

Literally hundreds of Detective instruments in the field attest to the performance and reliability of the technology.
