Personal Radiation Dose Alarm Meter

Personal Radiation Dose Alarm Meter is a compact, highly sensitive personal radiation dose alarm meter. It utilizes a new low-power embedded microprocessor as the data processing unit, with a highly sensitive GM counter as the detector. The instrument features fast response, a wide measurement range, and broad applicability. It can monitor X-rays, gamma rays, and hard beta radiation, making it a versatile radiation dose measuring instrument.
