FJ31-7103GN Multifunctional High Sensitivity Radiometric Neutron & Gamma Personal Dosimeter
I. product introduction
FJ31-7103GN is a multifunctional radiometric instrument with high sensitivity for rapid detection of gamma and neutron (selected) in unknown radioactive environment. It is the first choice alarm instrument used by environmental monitoring, homeland security, border ports, commodity inspection, customs, airport, fire control, emergency rescue, chemical defense force and other departments for routine survey and search for weak radioactive sources. This instrument can not only carry on all-weather monitoring and measurement alarm to radiation environment dose rate and dose, but also has powerful wireless transmission and integrated management function of background software.
