GAOTek Alarm Radiation Detector




GAOTek Alarm Radiation Detector The wrist-wrist personal dosimeter is an X-ray and γ-ray alarm instrument, which is mainly used to monitor the X-ray and γ-ray exposure doses received by workers in radioactive places. The dosimeter is small and can be worn like a watch. This dosimeter can be used in radioactive medical treatment, industrial non-destructive testing, radioisotope application, occupational disease prevention, military, nuclear power plants and radioactive workplaces and other occasions around the radiation dose equivalent measurement
