摘要：

The activity concentration of 210Poin atmospheric aerosol of Shenzhen and its committed effective dose through inhalation were studied. The activity concentrations of 210Po in total suspended particle (TSP) and PM2.5 were in the range of 0.01~0.20mBq/m3 (with an average of 0.08mBq/m3) and 0.03~0.38mBq/m3 (with an average of 0.12mBq/m3), respectively. The activity concentration of 210Po showed significant positive correlation with the atmospheric concentration of PM2.5, whereas it showed poor relationship with the amount of rainfall.It is suggested that the atmosphericparticle was the key factor that control the activity concentration of 210Po in the air. The calculated average annual committed effective dose of 210Po through inhalation was4.53×10-6Sv. © 2017, Editorial Board of China Environmental Science. All right reserved.
