Thanks to the good angular resolution of this binocular camera (360°), Damavan Imaging have developed a process to reconstruct gamma ray emission in 3D from at least 3 acquisitions.
Imaging is done in Compton mode from 300 KeV to 3000 KeV overlaid on “natural” (96 x 96°) field of view (FoV) optical images. Good angular resolution and image quality translates in more details reliably detected.
The most precise imaging is obtained in energy-gated mode gating on a specific isotope line.
In spectrometry and dosimetry, the high sensitivity CeBr3 spectrum is complemented by an energy resolved CZT spectrometric detector (1.5% on 137Cs) to allow reliable isotope identification in energy range 50 KeV-3 MeV with the help of a library, even in a completely "unknown" environment.
Energy and spatially resolved quantification of radiation can be done with the Compton head (300 KeV-3 000 KeV)
Temporal δ Delta can be used in nuclear power plants (NPP) in operation or in decommissioning, fuel and waste treatment and storage centers, transportation and logistics units, laboratories, etc. It is an ideal tool for locating radioactive hot-spots, characterizing sources and mapping an area for routine operations: It is also suitable for emergency situations and homeland security applications.
Damavan Imaging were selected to develop and provide a Compton Camera and technical work in the Sellafield nuclear decommissioning project. The camera will allow to quickly make a quantitative assessment of radiologic environment in order to better plan human intervention and waste disposal.
