Spid-X

A gamma ray spectro imaging device

Dedicated to nuclear environment

Markets & Applications

Product overview

In collaboration with the French Atomic Energy Commission (CEA), the Spectro Imager Spid-X has been designed for nuclear safety applications such as radioactive waste monitoring, decommissioning, decontamination or emergency situations.

The device offers fine spectroscopic capabilities embedding ultra-low noise ASICs and CdTe crystal thanks to 3D PLUS electronic components miniaturization technology.

The Spid-X gamma camera allows locating, identifying and measuring the dose intensity of the various radioactive sources that can be found in a nuclear environment. Combined with the small size and lightweight of the device, it brings a fast and efficient diagnostic on site, and can help the decontamination process.

Key benefits

Offers a high spectroscopic sensitivity for a quick and reliable detection of the radioisotopes.

Combines the analysis of key parameters such as location, identification, energy level of the radioisotopes and total ionizing dose.

Transfers the data of the hot points in real time.

Due to its low weight and small size, it is suitable for all kind of applications such as decommissioning, monitoring, waste management anddecontamination.

Offers 4 hours autonomy due to its low power consumption.

Allow customization of the high number pre-defined source mix.

Localization of Gamma sources

localization of am-241 and eu-152 sources in a nuclear waste barrel
  • Field of view of the coded mask
  • Localization of Am-241 (orange, 3.6 MBq per source) and Eu-152 sources (green, 10 MBq per source) in a standard nuclear waste barrel, placed 1 m from the device.
  • The identification of the sources is confirmed in less than 30 seconds and the angular resolution is better than 1° for each source
