| Abstract:: |
| Objective For providing the reliable evidences in monitoring a radionuclide released events,the techniques of identifying the characteristic radionuclides and its elimination of the interfering facors be promoted in a low level particulate air samples. Methods the methods for identifying characteristic radionuclides be introduced when the γ-ray spectrum is being analyzed,other interfering factors and their elimination methods be discussed,the calculation methods of minimum detectable activity and/or the sensitive threshold be listed. Results All of the radionuclides contained in two intercomparison samples had be identified,and our measurement results are closed to the reference values announced by IAEA. Conclusion As a results of tests in two intercomparison on radionuclids measurements organized by IAEA in 2002,it have proved that the methods introduced in the paper is creditable and reliable. |
