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.

  • Identifie, localizes and measure radioactive sources in real time
  • Determine the dose rate of each sources
  • Utilize dual-mode imaging technology: Coded mask aperture for low energies and Compton imaging for high energies
  • Access a wide range of up to 6 identifiable isotopes, customizable on demand
  • Operate with ease: compact dimensions [323 x 110 x 180 mm] and lightweight design [<3.5 kg]
