Pedestrian Portal Radiation Monitor

EI-G3920 Pedestrian&Luggage Portal Radiation Monitor

Product Introduction

EI-G3920  is a pedestrian & luggage monitoring system for detecting the radioactive materials and identifying the radionuclides. It performs rapid, convenient, sensitive detection and identification of Special Nuclear Materials(SNM), medical radionuclides, industrial radionuclides and Natural Occurring Radioactive Materials(NORM).


 High sensitive NaI(Tl) gamma detector
 High performance 6LiI(Eu) scintillator neutron detector optional
 Advanced and rapid spectroscopic analysis for SNM, medical radionuclide, industrial radionuclide and NORM detection and identification
 Automatic spectrum-stabilizing technique, high adaptability to circumstance
 Audible & visible alarm indication with adjustable alarm levels
