SPIR-ACE Radio Isotope Identification Device (RIID)

The SPIR-Ace unit is a versatile Radio Isotope Identification Devices (RIID) addressing all applications requiring efficient detection and identification of radiological threats in security applications, including civil defense, border security and customs. The SPIR-Ace device can be used in law enforcement, emergency response and other critical infrastructure applications. It also provides accurate assessment of nuclear materials for power plants, safeguard inspection, forensic laboratories and OSI/CTBTO agents.

The SPIR-Ace unit offers identification performance beyond current standards for RIIDs such as for heavily shielded isotopes, unbalanced mixtures of nuclides and Special Nuclear Material (SNM) masked by medicals or Naturally Occurring Radioactive Material (NORM) within a few seconds.

The SPIR-Ace device offers user-friendly and state-of-the-art features such as easy localization with directional indication, geo-localization and remote data transfer to a command center.
