Description
Bertin Technologies is an industrial group that develops high-performance instrumentation for critical
or scientific applications, such as defense & security, nuclear & health physics, and space.
The SaphyRAD product line is composed of a wide range of probes dedicated to the detection of all
types of particles (alpha, beta, neutron, and gamma). The latest developed probe is a portable
gamma spectrometer for in-situ measurement and radionuclide identification. Its algorithm is based
on a new analysis approach in gamma spectrometry. To perform this analysis, the algorithm needs
a GEANT4-simulated reference database of the probe. This database is composed of a single library
of forty spectral shapes for industrial and medical radionuclides, natural and fissile materials.
This algorithm is embedded in a microcontroller to allow in-field measurements. It has shown very
good identification performance with high confidence level, especially at low statistics (≤ 10,000
events in the whole spectrum), even with up to five radionuclides simultaneously. It also allows fissile
material classification (enrichment level for uranium and plutonium). Because of its ability to perform
analysis at low statistics, the measurement time can be reduced to a few seconds, allowing operators
to react quickly to the threat. This performance could be applied to other nuclear measurement fields,
such as nuclear installation monitoring and dismantling, research applications, and whole-body
radiometry.
