SPID-X : the new gamma camera
Innovation for nuclear environments’ safety
The SPID-X gamma camera is designed to simultaneously identify and locate radioactive sources, measure their energy levels, and determine dose rates.
This gamma spectro-imaging system delivers precise spectroscopic capabilities, allowing users to visualize and analyze radioactive hotspots and sources in real time.
The SPID-X integrates a specialized type of artificial intelligence called a convolutional neural network (CNN), specifically trained on radiation spectra. This advanced AI technology enables automatic detection of radionuclides even when peaks are partially obscured or when multiple sources are present.

Gamma source localization
Coded mask aperture imaging
Field of view demonstration using the coded mask technique.
- Localization of Am-241 sources (orange, 3.6 MBq each) and Eu-152 sources (green, 10 MBq each) in a standard waste barrel positioned 1 meter from the SPID-X.
- Source identifiaction occurs in less than 30 seconds with angular resolution better than 1° for each source
Compton Imaging
