Radiation Monitoring And Protection Instruments

HQ 80-B7 αβ Surface Contamination Meter

(92) Reviews

Product Description:

 HQ 80-B7 surface contamination instrument is suitable for the detection of α and β. The instrument adopts dual flash detector with high detection efficiency. It can measure α and β / γ simultaneously, and automatically distinguish α and β / γ detection results. It is an ideal instrument for α and β surface pollution detection in environmental laboratory, nuclear medicine, molecular biology, radiochemistry, nuclear raw material transportation, storage and commodity inspection. It is mainly used for occasions with high requirements for radiation monitoring, such as environmental monitoring (nuclear safety), radiological health monitoring (disease control, nuclear medicine), homeland security monitoring (customs), public safety monitoring (public security), nuclear power plant, laboratory and nuclear technology application and other occasions.
