Abstract Objective To understand and analyze aerosol radiation levels under hazy weather and normal weather in Lianyungang City.Methods The total α and β activity levels of airborne aerosol samples were monitored in haze days and non-haze days. A total of 44 samples were collected in the whole year.Results There was no statistically significant difference of the annual averages of total α or β activity between the haze days and non-haze days (P>0.05). In the spring and winter, the total α activity in the aerosol was higher than that of the autumn, and the difference was statistically significant (P<0.05).Conclusion On averages, there was no significant change of the total α or β activity in aerosols throughout a year, but the total α activity in the spring and winter seems higher than that in autumn. The radioactivity level in airborne aerosols in Lianyungang area was not abnormal.
