| Abstract: | The radionuclide monitoring data shall follow the safety and verification criteria based on the demand from international Radionuclide Monitoring Station by Comprehensive Test Ban Treaty. It was suggested that the activity and their ratio of ~(212)Ph, ~(214)Ph, ~(212)Bi, ~(208)T1 and some other radionuclides could be used for data verification criteria in aerosol sample collection. After using computer simulation,the minimum detectable concentration was given by different measuring time and different sampling flow rate. |
