| Abstract:: |
| Objective To measure and analyze the radioactivity level of 210Pb in outdoor air in Beijing in spring.Methods Portable high flow air samplers were used to collect outdoor air at the ground level to analyze the 210Pb radioactivity in the aerosol filter samples using a laboratory-based high purity germanium (HPGe) γ spectrometer. Results The activity concentration of 210Pb outdoors ranged from 267.2 to 1 697.6 μBq/m3, with an average of (878.7±386.7) μBq/m3. Statistical analysis showed that the activity concentrations 210Pb of outdoors varied with variable air quality. Conclusions The activity concentrations of 210Pb outdoors are detectable in Beijing, varying considerably but within the normal range. |
