Model GSP-2 NaI Scintillation Detector

MicroR Detector, sensitive 2"x2" Crystal, for Gamma and X-ray

GSP-2 NaI Scintillation detector by Johnson Nuclear

The Model GSP-2 is recommended for moderate energy gamma detection. The larger detector crystal greatly enhances the sensitivity. Energy response ranges from 50 keV to 2 MeV. This 2"x2" sodium iodide detector is recommended for use with  channel analyzers. The detector is housed in a rugged aluminum housing with magnetic shielding. A BNC connector is included for easy field replacement.
