R-EGD portableRadiation detectorIt is a portable radiation detection instrument used for measuring x and gamma rays. It uses G-M counting tubes as detectors, with fast response speed. Compared with similar instruments in China, this instrument has a wider dose rate measurement range. This instrument can not only measure high-energy and low-energy gamma rays, but also accurately measure low-energy X-rays, with good energy response characteristics. The R-EGD portable radiation detector can be widely used for radiation protection monitoring in environmental monitoring, health and epidemic prevention, import and export inspection, radiation medicine, building materials, petrochemicals, geological survey, scrap steel, nuclear laboratories and other fields, as well as radiation security inspection in airports, stations, ports and other fields.

Performance characteristics:

1. High sensitivity, wide measurement range, and excellent energy response characteristics.

2. High speed low-power microprocessor unit.

3. Dose and dose rate digital display.
