| Objective To detect the aerosol samples that were collected by high flux air sampler with γ-spectrum calibration techniques. Methods Energy-calibration and efficiency-calibration were performed with a standardized mixed radionuclide source provided by National Physical Laboratory, UK. And a curve imitate method was established for radionuclide measurement. Results The energy-linearity of γ-spectrum measuring system was good, and the detection efficiency could meet the measurement requirement. Conclusions As the speciality of aerosol samples, concerned it is necessary to carefully calibrate the measuring system in order to improve the reliability of the measured results. |
