CAEN Gamma stream is a compact and portable system for gamma ray spectroscopy with scintillation detectors, which provides an active Multi-Channel Analyzer (MCA) integrated in a 14-pin photo-multiplier tube (PMT) base. Gamma stream fully integrates in a stand-alone device the high voltage to bias the PMT, the preamplifier to shape the signal from detector, and the MCA for a complete Pulse Height Analysis online. Gamma stream makes easy the measurements with scintillation detectors NaI(Tl) [0.3l] with no need of additional cables.

The measurement can be run with a tablet in just one click!

The backpack includes a Tablet 10″ through which a series of outdoor measurements can be performed. With the GammaEDU Android application the user can acquire and analyse in real time a γ-ray spectrum to get the K, U and Th abundances, keep track of the surrounding environment, take the GPS coordinates and shoot a picture of the on-going measurements. The data are saved in a .kmz file ready to be visualized on Google Earth and shared for producing a radioactivity map of the area.

Applications

• Customs protection and border control
• Educational experiments and surveys
• Mapping of potential radon-prone areas
• Environmental monitoring in land field
• Geochemical and mineral exploration
• Scenario of emergency services
• Homeland security
