A record of atmospheric 210Pb accumulation in the industrial city
Abstract
The deposition flux of total atmospheric 210Pb in the industrial city Rostov-on-Don, Russia from 2002 to 2010 has been measured. The variations in annual 210Pb deposition flux appear to be mainly correlated with the number of rains and significant amount of anthropogenic 210Pb, polluted into the surface layer of air in the home-heating period. The average 210Pb deposition is 1.75 mBq/m3. Several meteorological parameters which are strongly associated with the fluctuations of concentrations of 210Pb are identified. These results are useful to provide typical information on the atmosphere radioactivity in an industrial city.
