GSP-1 NaI Scintillation Probe

GSP-1 NaI Scintillation probe by wb johnson

The GSP-1 Scintillation probe is useful for moderate energy gamma survey at the microR level. Energy response ranges from 50 keV to 2 MeV. The GSP-1 will function well with most survey meters, ratemeters, single channel analyzers, and multi-channel analyzers. This scintillation detector is commonly used with Johnson Nuclear Survey Meters. This Sodium Iodide probe features rugged aluminum housing with magnetic shielding. The BNC connector allows for easy field replacement.
