Radioactive aerosols as tracers in the study of atmospheric pollution

Abstract

The aim of the current PhD thesis is the determination of the atmospheric concentrations of radioactive isotopes and trace elements in air filter samples collected from the Helsinki metropolitan area, in Finland from 1962 to 2005.16070 daily aerosol samples (Whatman GF/A, 3500 m^-3 d^-1) were collected in FMI facilities, in order to monitoring natural radioactivity. Simultaneously, 608 weekly aerosol samples of air filters were collected by means of an aerosol beta radioactivity monitoring system, for the determination of trace elements in the atmosphere. Based on such a large set of data and by studying the elemental and radioactive concentrations (especially of 210Pb) in aerosol filters collected in the capital of Finland, the evaluation of the influence of different pollutants with anthropogenic origin on the atmosphere and generally on the environment can be achieved. For that reason, the extent to which information concerning the specific activity (210Pb/Pb) of lead can help in un ...
