The invention belongs to the field of
radiation protection, and provides a
system platform for calibrating radioactive
aerosol monitoring equipment and a working method thereof. The platform comprises an
aerosol generation device, a standard
aerosol activity concentration measurement device, a to-be-calibrated aerosol monitoring
equipment device, an aerosol recycling device, an
electrical control and monitor console, and the like. According to the invention, radioactive aerosol generated by the aerosol generation device simultaneously flows through the standard aerosol
activity concentration measurement device and the to-be-calibrated aerosol monitoring
equipment device, the obtained
radioactive activity concentration is equal, the standard aerosol
activity concentration measurement device goes through standard measurement and can accurately measure the activity concentration values of gaseous radioactive aerosol of different activity levels and different types, and thus, a to-be-calibrated
detector can be calibrated. The
system platform has the advantages of dynamic calibration, high precision, adjustable measurement range, synchronous measurement by the standard device and the to-be-calibrated device, applicability to online monitoring and offline monitoring, and the like.
