Overview

EFO Portable Radiation Survey is for measuring x-ray and gamma rays. It uses a GM counter tube as a detector, which is fast and has a wider range of similar instruments. The instrument is in addition to measuring high energy, low energy gamma rays, but also on the low-energy X-ray measurement, with good energy response characteristics. R-EGD portable radiation detector can be widely used in environmental monitoring, health and epidemic prevention, import and export commodity inspection, radiation medical, building materials, petrochemical, geological survey, scrap steel, nuclear laboratories and other areas of radiation protection monitoring.
