OSIRIS Gamma-Ray Spectrometer

The OSIRIS Gamma-Ray Spectrometer for Nuclear On-Site Inspections under the CTBT (OSIRIS) is an instrument that can detect radioactive material and other nuclear explosive devices.
The On-Site Inspection RadioIsotopic Spectroscopy (OSIRIS) system was designed to collect evidence of nuclear explosions in accordance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
The OSIRIS system is a measurement-restriction approach that limits information displayed on radioisotopes to 17 specific fission products, with half-lives ranging from days to years. They have been identified by a group of international technical experts as being relevant to the detection and identification of a nuclear explosion during an on-site inspection for the Comprehensive Test Ban Treaty.

Other OSIRIS features include:

• Automatic spectral data interpretation, in real time.
• Only summary information presented to the operators. Raw spectral data files are stored to hard disk after encryption using the Advanced Encryption Standard-128.
• Automatic energy calibration from Eu-152, Th-228, or natural background gamma rays.
• No liquid nitrogen required.
• Seven-hour spectrometer battery lifetime, battery may be “hot-swapped” while the spectrometer is in operation.
• OSIRIS software works with Windows 7 and Windows 10 operating systems.

The OSIRIS program was jointly developed and tested by Idaho National Laboratory, Lawrence Livermore National Laboratory and Pacific Northwest National Laboratory. Further information can be found in a recent peer-reviewed technical publication.

OSIRIS is now a commercial product available from ORTEC.

OSIRIS features:
