In order to solve the problem of on-site calibration of online tritium monitor,the research of on-site calibration method of online tritium monitor was carried out in this paper,including the mechanical structure,working principle of the on-site calibration device,the determination of the calibration device value,and the calibration items to be carried out.At the same time,the same online tritium monitor was calibrated and compared,using the on-site calibration device and the standard device of tritium activity concentration.The results showed that the calibration factors of the two devices were 1.07 and 1.05,and the relative deviation was 2％.The on-site calibration device had the ability of quantity transfer and could meet the requirements of field calibration.In addition,it had the characteristics of portability,operability and separability,which could ensure that on-site calibration was not limited by the working space of the site,was suitable for on-site calibration experiments,which could solve the problem of untraceable online tritium monitoring equipment.
