SW82-type X-γ ray radiation Dose Alarm 
 Ultra-low-power embedded devices using a microprocessor as a data processing unit, the detector uses a highly sensitive GM counter, fast response, wide measurement range of features. Can be monitored X, γ rays and β-ray hardware. Generally applicable to nuclear power plants, accelerators, isotope applications, industrial X, γ nondestructive testing, medical radiation, cobalt source treatment, γ irradiation, radioactive laboratories, environmental monitoring around nuclear facilities in areas such as the alarm in time to give directions to ensure the safety of staff .
