Abstract

A calibration system was designed to meet the calibration requirement of the radioactive aerosal monitors. The system consists of a radioactive aerosol generation unit, a dilution and mixing unit, a sampling and measuring unit, a purification unit and an automatic control unit. The commonly-used α and β radioactive solutions Am(NO3)3 and CsCl were selected to prepared different concentrations of monodisperse radioactive aerosol. After testing the calibration system, it was determined that the measurement uncertainty of the α and β efficiency calibration factors taken by the system for the radioactive aerosol monitor was 2.8% and 2.6%, respectively.
