SPIR-ACE
Radionuclide Identification Device
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 inspections, and forensic laboratories.
The SPIR-Ace unit is a versatile Radio Isotope Identification Device (RIID) addressing all applications requiring efficient detection and identification of radiological threats in security applications, including civil defense, border security and customs.
The device, coupled with offline Genie software, becomes a highly portable and powerful instrument for in situ measurement applications. The direct compatibility with Genie (CNF), ISOCS efficiency characterization, and onboard geometry selection, enables efficient quantitative assessment.
Ultra fast and accurate search and nuclide identification
Identifies heavily shielded materials, unbalanced mixes, and Special Nuclear Materials masking scenarios
Generic ISOCS characterization, preloaded efficiency calibrations
Connects to Genie for immediate and easy quantification
Identify
The screen provides all the information to evaluate the situation, with no button to touch.
Detect
Detection of higher gamma or neutron rates activate the screen, generate alarms. The device provides continuous nuclide identification.
Locate
The SPIR-Ace unit offers on-device identification performance beyond current standards for RIIDs such as for heavily shielded isotopes, unbalanced mixtures of nuclides and Special Nuclear Material
Search
Use the Radar and Histogram screens to localize a source, and map the geolocation of the hotspot area.
Remote Display and Start
Connect to the SPIR-Ace device with a hotspot or Wi-Fi connection and enable acquisition from a safe or more accessible location.
